Hotel Fun Fact: At three months old, the St. Regis Costa Mujeres is already one of the most anticipated new luxury openings in Mexico — and we were there before the world found it!
- Brand new — and it shows – Opened June 2026. Everything still smells new. The staff are energized. The GM introduced herself at check-in. This is a rare window to experience a world-class resort before it’s fully discovered.
- Fish Market — the best restaurant on property – Baja California oysters that needed no crackers, no hot sauce, nothing. Steaks, halibut, guacamole. We ate here more than anywhere else on the property and would have eaten here every meal if we could.
- Hydrotherapy circuit — genuinely unlike anything else – Six stations, each six minutes: sauna, cold bucket shower, steam room with frozen aloe ice cubes, cold plunge, bubble foot massage pool, and a three-headed pressure shower wall. Nothing we’d experienced before.
- Champagne sabering at 6 PM — every single night – The entire staff from management down participates. We didn’t miss a single night. Dasa and the team personally walked around delivering champagne and having real conversations about the property.
- Pool service from Isaac, Ada, Adrian and Arath – When we arrived at the pool before breakfast had ended, Isaac went directly to the kitchen chef and had a dish made off-menu for us. That’s the level of attention we experienced every single day.
- The floor plan guide you can’t find anywhere else – Three different John Jacob Astor Suite configurations, pool type breakdowns by floor, residency levels — none of this is explained clearly online. We stayed in two different room types across two visits and have the full picture.
- The hotel is 25 minutes north of Cancun airport. The hotel offers a direct pickup — a large Suburban, $150 one way. The driver met us at the exit after baggage claim, loaded everything, and drove us straight there. Worth arranging in advance.
- For context: the St. Regis Kanai Riviera Maya is about 40 minutes south of Cancun airport — making the two St. Regis properties roughly an hour apart by car. Two very different experiences of the St. Regis brand in Mexico.
- Floors 1–4 are the hotel. Floors 5–12 are residences. This is the most important thing to understand before booking. The residences were not yet open during our October visit — they’re opening November/December 2026. This directly affects which rooms and pools you can access.
- Pool type depends entirely on floor: Ground floor (floor 1) = private pools. Floors 2–4 selected rooms = plunge pools. Floors 2–4 standard rooms = terrace only. Floor 12 residences = large private pools. Choose carefully before booking.The Butler’s Pantry in the John Jacob Astor Suite is a side-entry kitchen hatch that lets the hotel deliver food and remove dishes without ever coming through your main front door. A small detail that makes a meaningful difference when you’re hosting or just want privacy.
- The entire ground floor is open-air connected — every time you move between restaurants, the boutique, the bar, the pool, or your ground floor room, you’re technically outside under covered lobby ceilings. In summer, expect humidity throughout these transitions.
- Champagne sabering is at 6 PM every evening in the lobby. The entire staff participates — management included. We didn’t miss a single night. Don’t skip it.
- Three more restaurants are coming soon: a speakeasy being built underground (we got a tour — it’s going to be spectacular), an Italian restaurant on the hotel corner, and a Japanese restaurant on the fifth floor next to the new adult pool.

Arriving at the St. Regis Costa Mujeres: Check-In with Sheydi, Dasa, and the Butler Team
The hotel arranged our pickup directly — a large Suburban waiting at the airport exit, $150 one way, driver already there as we came out with luggage. Forty-five minutes north of the airport, past the busier stretches of the Hotel Zone, and the St. Regis Costa Mujeres materializes out of the coastal landscape. Security at the front gate, a short driveway, and then the grand open lobby entrance opens up in front of you — high ceilings, all doors thrown open to the outside, a unique sculptural fountain at the center that reads as a slight optical illusion depending on where you’re standing. It stops you for a moment.
Before we even fully processed the lobby, a cold towel and a welcome drink appeared. We were seated at reception with Sheydi, who checked us in with the kind of warmth and attentiveness that makes you immediately feel like you’re somewhere that has thought carefully about how guests should be treated. Mid-check-in, the general manager Dasa came over to introduce herself personally — letting us know that she and her entire team were genuinely excited to have us there. You don’t often get that. At a brand-new property with fresh energy throughout the staff, it felt completely sincere.
We were then introduced to our butlers, Ingrid and Christopher, who would be giving us a tour and walking us to the room. The same energy that Jose at the door had while handling our bags, that Sheydi had at the desk, that Dasa brought when she came over — Ingrid and Christopher carried that same warmth throughout our entire stay. It set a tone that held for everything that followed.
Before heading to the room, Ingrid and Christopher walked us through the property layout — because honestly, without a guided orientation, this hotel is not immediately intuitive. We’ll get to the full floor plan breakdown next, because it’s the thing we wish we’d known before arriving.
St. Regis Costa Mujeres Floor Plan: Hotel Floors, Residences, and Which Rooms Have Pools
This section is the most important part of the review if you’re considering booking the St. Regis Costa Mujeres Resort — because when we researched before our first trip, none of this was explained clearly anywhere online. We’re going to be the first to explain it properly.
- Critical booking context: The hotel shares its building with residential units. Floors 1–4 are the hotel. Floors 5–12 are branded residences opening November/December 2026. This directly determines which rooms, pool types, and amenities you can access.
| Floor(s) | What’s There | Pool Type |
|---|---|---|
| Floor 1 (Lobby) Hotel | All common areas — reception, concierge, boutique, fitness center, Kids Zone, Olivia Coffee Bar, St. Regis Bar, Tea Room, Costa Coral restaurant, Fish Market, Zaytinya restaurant, Astor Ballroom. Spa is one floor below via elevator. Second half of floor 1 is hotel rooms. | Private pool — full-size, roughly 20×25 ft, infinity edge. These are the most sought-after room type on property. |
| Floors 2–4 Hotel | All standard hotel guest rooms and suites including the John Jacob Astor suite categories. | Selected rooms: plunge pool. All other rooms: terrace only. No full private pools on these floors. |
| Floor 5 Mixed | Adults-only pool (hotel guests, no children). New Japanese restaurant opening adjacent. Second pool on opposite side for residents only — hotel guests cannot access this one. | Adult pool open to hotel guests. Resident pool: residents/booked residences only. |
| Floors 6–12 Residences | Branded residential units — private elevator access, residential concierge, full resort amenity access. Opening November/December 2026. | Large private pools — the biggest on property, primarily on floor 12. Not accessible to hotel guests. |
The reason this matters: before our first visit, we assumed the top floor of the hotel building meant the best suites with rooftop pools — the way it works at many resorts. That’s not how this property is configured. The top hotel floor is floor 4. The large pools at the top of the building belong to the residences. If you want a room with a private pool at this hotel, your only option is the ground floor. If you want a plunge pool, select rooms on floors 2–4 have them. Everything else on floors 2–4 is terrace only.
- Book early and be specific about pool type in your reservation. The ground floor private pool rooms are the most limited inventory on property and the most in demand. The “Grand Deluxe” descriptor on the booking page refers to the ground floor pool rooms — but the description doesn’t make that clear at all.
John Jacob Astor Suite at the St. Regis Costa Mujeres: Three Layouts Compared
John Jacob Astor Suite — Terrace-Only, Oceanfront
John Jacob Astor Suite — Terrace + Plunge Pool
2 Bedroom Suite, Bedroom 1: 1 King, Bedroom 2: 2 Queen, Ocean view, Terrace & Private Pool
John Jacob Astor Suite — Terrace + Private Pool
2 Bedroom Suite, Bedroom 1: 1 King, Bedroom 2: 1 King, Ocean view, Large Private Pool
Two bedrooms, same configuration as above, but located at the very corner of the hotel on the ground floor with a large private pool — not a plunge pool. Only two of these exist on the entire property (limited availability). If you want the John Jacob Astor Suite experience with a real private pool, this is the one. Getting it will be a challenge given the limited inventory, but it’s the version that combines the suite footprint with the full ground floor pool experience.
On our second visit, we skipped the large suite altogether and booked a Grand Deluxe 2 Queen ground floor room to get the private pool experience. The room itself is normal hotel room size — “Grand Deluxe” is the descriptor on the site but it doesn’t reflect something meaningfully special about the room. You walk in, coffee bar and cabinets along the left wall, large walk-in bathroom with garden tub.
What you’re paying for is the entire back wall of the room opening completely into your private pool and patio. When that sliding door is wide open, you’re essentially inside-outside — the room becomes a continuous space from the bed to the pool. The pool is roughly 20×25 feet, with the first 10 feet very shallow (lounging depth) and the back 10 feet at a full 3.9 feet deep. Each pool is an infinity edge that channels into a shared run in front of the rooms.
Our specific view was partially blocked by trees, but honestly the privacy that came with the greenery gave it a Tulum-like energy we ended up really loving.
We stayed in Room 460 (center JJA suite, floor 4, no pool) and our friend was simultaneously in Room 360 (corner JJA suite, floor 3, plunge pool). If it’s your first visit and pool access isn’t critical, go for Room 460 — it’s the more spacious and visually satisfying of the two. If you want a private pool in a suite, the ground floor JJA corner is the only option and there are only two on property.

Restaurants at the St. Regis Costa Mujeres Resort: Fish Market, Costa Coral, Palmare Grill and More
Fish Market
This was our favorite restaurant on the entire property — no question. An outdoor setting with all the blinds and doors wide open, ocean breeze coming through constantly, and a menu that was better than we expected from a hotel pool restaurant. The oysters are from Baja California and they’re some of the best I’ve eaten anywhere. I’m particular about my oysters — I normally prefer East Coast over West Coast — but these needed nothing. No cracker, no hot sauce, nothing added. Absolutely delicious on their own. Beyond the oysters: excellent steaks for dinner, halibut, and the guacamole is a must-order.
If you’re sitting around the pool, technically the kitchen serves the pool area — but we specifically requested dishes from the Fish Market menu because we preferred it. Order from here even if you’re poolside.
Costa Coral Restaurant
The main restaurant for breakfast and dinner, with both a full menu and a buffet running simultaneously. Breakfast here is fantastic — everything made to order from the menu, an omelet station at the buffet, and indoor plus outdoor seating available.
Our recommendation: arrive right when they open at 7 AM if you want the cooler morning temperature and your pick of tables. The indoor space is well air-conditioned. We didn’t eat dinner here, but this is clearly the quieter, more family-friendly option for evening dining versus the livelier Fish Market or St. Regis Bar.
Palmare Grill
Palmare is tucked down along the ocean and you genuinely cannot see it from the hotel pool or lobby — it’s hidden behind the beach access path. Don’t skip it because you don’t know it’s there.
The ribeye tacos are outstanding. We had them almost every single day of both visits. The setting is casual, beachside, open-air, and the menu leans toward lighter beach fare that’s exactly right for a midday meal between swims. We actually ordered from the Palmare Grill menu while sitting at the main pool on multiple occasions by specifically requesting it — worth asking the pool staff if that option is available during your visit.
St. Regis Bar
Every St. Regis has a bar that’s distinctly its own, and this one earns its place in that tradition. Two sides to the bar — one with a full crafted cocktail and specialty tequila menu, another dedicated to the free nightly tequila tasting hosted by Jonathan, their bartender who clearly knows exactly what he’s doing.
We ate tapas here our first night, did the tequila tasting with Jonathan on the second side of the bar, and kept coming back throughout both stays to sit, play cards, and just exist somewhere beautifully decorated. Jonathan is the reason to come. The tequila tasting is complimentary and runs every night at 8:45 PM — don’t miss it.
Olivia Coffee Bar
Zaytinya, Mediterranean — Coming Soon
The Italian restaurant is visible from the lobby area currently being finished with fireplaces and décor, sitting at the corner edge of the hotel.
Shami Japanese Rooftop — Coming Soon
Japanese: 5th floor next to adult pool
Shami, the Japanese restaurant, will open on the fifth floor next to the new adult pool, giving dinner service an elevated ocean view from above.
Jack’s Club Speakeasy — Coming Soon
Speakeasy: underground, basement level
We got a private tour of the underground speakeasy being built in the basement — photos weren’t allowed, but it’s going to be spectacular. 30 seat private jazz club, hotel guests only.
Pools at the St. Regis Costa Mujeres: Main, Private, Plunge, and Adults-Only
There are more pools at this property than most guests realize going in. Here’s the full picture so you can plan accordingly.
The main pool is a large infinity pool facing the ocean — the centerpiece of the property. It’s cooled in summer the same way the pools at Encore at Wynn or Four Seasons Hotel Las Vegas are, which makes it genuinely comfortable during the heat of the day rather than the warm soak most Mexican resort pools become by noon. Inside the pool, there are in-water bar seats where you can order cocktails, though you cannot order food from inside the pool — if you want food you need to be at the pool deck.
On either side of the bar in the pool are two hot tubs — but these aren’t temperature-controlled hot tubs in the traditional sense. They run at ambient temperature, which makes them a comfortable lukewarm rather than genuinely hot.
To the right of the main pool is a very shallow children’s pool that maxes out at 1.8 feet deep, which is also perfectly usable by adults who just want to lay nearly flat in water.
The service at the main pool was honestly the most memorable part of both stays. Adrian and Arath handled towels, water, and umbrella adjustments every day without ever needing to be asked. Isaac was in a category of his own. One morning we arrived at the pool before breakfast had finished and decided to skip the restaurant — Isaac didn’t hesitate. He and Ada went directly to the breakfast kitchen chef and had a dish cooked completely off menu for us. We weren’t expecting it and hadn’t asked for anything special. That’s just the standard they operate at. Throughout both stays, Omar brought us complimentary ice cream treats, Isaac and Ada brought out churros and chocolate while we were in the pool, and the mezcalita service was consistently excellent. When pool service is this good, you don’t leave the pool.
- The main pool bar cannot serve food while you are in the water — only cocktails. If you want food while at the pool, you need to be seated on the outside pool bar or on the pool deck. Alternatively, ask your pool server whether they can bring dishes from the Fish Market or Palmare Grill menus poolside.

St. Regis Costa Mujeres Spa: The Hydrotherapy Circuit Station by Station
The spa is one floor below the lobby level, accessible via the elevator near the fitness center. Walking through the large spa doors, you’re immediately in a different environment — calm, beautifully designed, a quality of quiet that the rest of the resort doesn’t have. We checked in with our spa butler Daniel, who handed us welcome champagne and walked us through the process before we changed into robes and slippers in the large, fully stocked locker rooms.
The hydrotherapy circuit is what distinguishes this spa from most of what we’ve experienced at luxury hotels, and we want to describe it in detail because nothing we’d read beforehand prepared us for it.
The circuit runs through six stations, each approximately six minutes:
Station 1 — Hot sauna. Lay back, cucumber and cold towel over the eyes, let the body temperature rise fully before anything else.
Station 2 — Cold bucket shower. A closed standing shower facing each other. You pull a chain. A full bucket of cold water drops over your head. Your body temperature drops immediately and completely.
Station 3 — Steam room with frozen aloe vera ice cubes. They hand you small frozen cubes of aloe vera and you massage them over your entire body while the steam works around you. This was something entirely new to us and genuinely remarkable — the cold aloe against the heat of the steam is a combination we hadn’t encountered anywhere.
Station 4 — Cold plunge pool. Not ice water, but genuinely cold. We stayed for the full six minutes and the reset it produced going into the next station made it worthwhile.
Station 5 — Hot Jacuzzi. A proper hot soak. Rest, recover, let the contrast from the cold plunge work through you.
Station 6 — Bubble foot and leg massage pool. Two standing stalls inside a pool where very small bubbles are released at your feet and legs. Six minutes of standing there while the bubbles massaged from the ankle up.
Station 7 — Three-headed shower wall. Three different shower heads targeting different zones: one forces water hard enough to massage the mid-to-lower back, another sends calming flow over the head and neck, a third is more forceful for the shoulders and upper back.
Station 8 — Bubble back massage bed. You lay down in a metal bed inside a pool and bubbles are forced across your entire upper back. The most calming station of the whole circuit.
After hydrotherapy we changed, sat in the lounge with warm tea, and were called in for a 60-minute couples deep tissue massage. I had a sunburn on my upper shoulder and flagged it — they adjusted completely, focused on back, legs, and front body as requested. The therapists listened. The standard note about massages applies here: 60 minutes feels long while it’s happening and not nearly long enough when it’s over. Book 90 if you can. Our spa butler Daniel made the entire experience feel personally guided rather than operationally processed. Highly recommend!
Beach, Fitness Center, and Champagne Sabering at the St. Regis Costa Mujeres
The Beach
The beach at the St. Regis Costa Mujeres splits into two distinct sections. The main beach area houses the Palmare Grill, multi-level decking with sitting areas, beach chairs along the oceanfront, and the large dock that extends into the water with two small gazebos and a large covered gazebo at the end containing a full bar area and private dining during busy season. We were offered dinner out on the dock during our stay — which we unfortunately didn’t take them up on but plan to on a return visit.
Kayaks and paddleboards are available between the two areas — including clear-bottom kayaks, the kind we’ve seen at the Ritz-Carlton Maldives, which are genuinely special when the water is clear enough to see beneath you.
Beach Club
The beach club section sits down and off to the left, separated from the main beach by the lifeguard tower. It is intended to welcome outside visitors while maintaining dedicated beachfront space for hotel guests.
The beach club has its own color-coded umbrella system (white/khaki for the main beach, striped for the beach club), plus two massive Jacuzzis built into the hillside and multi-tier seating on the embankment for those who want to be elevated above the sand.
The Fitness Center
Called Fit — is impressive for a three-month-old property. Treadmills, Stairmasters, full bodybuilding machines, and kettlebells (which are genuinely hard to find at most hotel gyms). There’s also an outdoor section for calisthenics and CrossFit-style movements. Worth noting: the outdoor gym section is exposed to the humidity. In October it was manageable. In peak summer, it would be brutal. The indoor section is air-conditioned and was always available and empty during our visit.
Kids Zone
The Kids Zone is genuinely well designed — movies, pool table, foosball, and other games in a dedicated indoor space for families. Whether you have kids or not, it’s a thoughtful amenity that signals how family-ready this property is becoming.
Champagne Sabering
And then there’s the 6 PM champagne sabering — the same ritual the St. Regis brand has performed since John Jacob Astor IV established it at the New York property in 1904. At the St. Regis Costa Mujeres, the entire staff participates: management, butlers, servers, everyone. Dasa and the team walked around personally delivering champagne, having real conversations with guests, making the place feel like a community rather than a transaction. We attended every single night of both stays and never found it repetitive. At a brand-new property with a team this engaged in what they’re building, the sabering felt like something more than a ritual — it felt like a celebration of where they were.
Our Verdict on the St. Regis Costa Mujeres Resort After Two Stays
We enjoyed the St. Regis Costa Mujeres so much on our first visit that when a hurricane delayed our onward travel five days later, we didn’t hesitate — we went straight back. That’s the most honest endorsement we can give a hotel.
At three months old, the property is still becoming itself. Three restaurants haven’t opened yet. The residences are still coming online. Some of the pool deck decor is still being finalized. And despite all of that, the core experience — the Fish Market oysters, the hydrotherapy circuit with Daniel, Isaac and Ada making off-menu dishes happen at the pool, Jonathan’s nightly tequila tasting, Sheydi at check-in, Dasa coming out to welcome us personally, the champagne sabering with the full team every evening — was already at a level that made us reluctant to leave either time.
Book it now, before the world catches up to it. Use the floor plan guide in this review to choose your room type correctly. Eat at the Fish Market every day. Do the hydrotherapy. Be at the bar at 8:45 PM for Jonathan. And be in the lobby at 6 PM every evening without exception.
