This region's 2026 story splits in two. Mexico is delivering: a Park Hyatt open, an Alila open, a St. Regis and an Aman with confirmed dates inside the next eight weeks. The islands are slipping: the Caribbean's two most watched projects have both moved off their announced windows. Every status below was checked in June 2026 against the operator, the brand newsroom or dated trade reporting, and where a date is a target rather than a fact, the label says so.
Where does the regional calendar stand?
Ten properties, two countries' worth of momentum and three cautionary tales. Status verified June 2026.
| Hotel | Place | Status | Keys |
|---|---|---|---|
| Park Hyatt Cabo del Sol | Los Cabos | Open (Dec 15, 2025) | 163 |
| Four Seasons Puerto Rico | Bahia Beach | Open (Nov 20, 2025) | 139 |
| Alila Mayakoba | Riviera Maya | Open (Feb 2026) | 182 |
| St. Regis Costa Mujeres | Cancun | July 17, 2026, confirmed | 160 + 80 residences |
| Amanvari | East Cape, Baja | Aug 1, 2026, confirmed | 18 |
| St. Regis Los Cabos | Quivira | Summer 2026, announced | 120 + 60 residences |
| Andaz Turks & Caicos | Grace Bay | Slipped (now Oct 2026 reported) | 59 + 74 residences |
| Six Senses Grand Bahama | Grand Bahama | Slipped (Q4 2026 official, unstarted) | n/a |
| Kimpton Turks & Caicos | The Bight | 2027, announced | 192 |
| Four Seasons Cayo Largo | Fajardo, PR | No date published | n/a |
Which of these hotels can you book tonight?
Three, and each one is a brand planting a first flag or reclaiming an address.
Park Hyatt Cabo del Sol (Los Cabos)
Open since December 15, 2025. The first Park Hyatt in Mexico put 163 rooms, 88 of them suites plus three villas, on the Cabo del Sol stretch of the Tourist Corridor, with architecture by Sordo Madaleno built around courtyards and timber rather than the usual Baja megablock. The honest caveat: it opened into an extended soft phase, with some signature venues and amenities trailing the first guests by months, so ask what is actually operating in your travel week before paying the full rack rate. Our Los Cabos hotel guide ranks the incumbents it has to unseat.
Four Seasons Resort and Residences Puerto Rico (Bahia Beach)
Open since November 20, 2025. This is the former St. Regis Bahia Beach reflagged after a 140-million-dollar renovation: 139 redone rooms and suites, ten food and beverage venues, two pools, a nature reserve setting on the northeast coast about 40 minutes from San Juan. The honest caveat: the property has published a further renovation window from June 19 to October 24, 2026, with work during business hours, which overlaps almost exactly with hurricane season. Book it from late autumn instead, and compare it first against the city options in our San Juan hotel guide.
Alila Mayakoba (Riviera Maya)
Open since February 2026. Alila's Latin America debut is a renovation and reflag of the former Andaz Mayakoba: 182 rooms and suites inside the lagoon-laced Mayakoba enclave it shares with Rosewood, Banyan Tree and Fairmont. The honest caveat: this is a conversion wearing a new name, not a ground-up build, and as of our June check the brand had not settled whether the property goes adults-only. Families should confirm the policy directly before booking. The neighborhood context is in our Riviera Maya hotel guide.
Which openings have real dates this summer?
Two, both in Mexico, both inside the next eight weeks, and both taking reservations now.
The St. Regis Costa Mujeres Resort, Cancun
Confirmed for July 17, 2026. The first St. Regis for the Cancun coast takes the quieter Costa Mujeres strip north of the hotel zone: 160 rooms and suites, each with outdoor space, plus 80 branded residences, several pools and the brand's 24-hour butler program. Worth noting: reservations originally pointed at June 25, so the date has already moved once, by three weeks. The honest caveat: July 17 lands the opening squarely in hurricane season, which is why opening rates will look generous; the property's first real test is the winter. Our Cancun hotel guide covers what it joins.
Amanvari (East Cape, Baja California Sur)
Confirmed for August 1, 2026, and taking reservations. Aman's first Mexican resort is the smallest entry on this list by far: 18 casitas, most around 833 square feet with private heated pools, raised on stilts over the dunes of the 1,500-acre Costa Palmas development it shares with a Four Seasons. The history deserves a label of its own: announced in 2018 for 2020, it opens roughly six years late. The honest caveat: August is the East Cape's hottest, stickiest month, and a project with a six-year slip has earned a verify-before-you-fly rule even with a confirmed date. We track it alongside the rest of the pipeline overview.
What has a window but no date?
The St. Regis Los Cabos at Quivira
Announced for summer 2026, no day published. Marriott's second Baja St. Regis project sits above the Quivira golf course on 33 acres with 1,200 feet of Pacific frontage: 120 rooms, 60 residences, architecture by SB Architects. The honest caveat: with the Costa Mujeres sibling consuming the brand's July attention and no published day as of June, a "summer" window this late in the year routinely becomes autumn. Do not book a special occasion against it yet.
Which Caribbean projects slipped, and how badly?
The conclusion first: the two most anticipated island builds of 2026 are now an October question and an open question, respectively.
Andaz Turks & Caicos at Grace Bay
Slipped: latest reporting says October 2026. The first Andaz in the Caribbean, and Hyatt's first hotel in Turks and Caicos, pairs 59 rooms with 74 residences on Grace Bay beach. Coverage through early 2026 said May; the building topped off, but the most recent reporting moved the opening to October. The honest caveat: a five-month slip announced this close to opening usually means the residences closed first and the hotel inventory follows, so re-verify before booking anything for late 2026. The proven alternatives are in our Turks and Caicos hotel guide.
Six Senses Grand Bahama
Slipped, and we would plan no stay around it. The official target remains fourth quarter 2026 for the 250-million-dollar resort and residences at Barbary Beach, backed by Weller Development Partners and Pegasus Capital Advisors. But island press reported in January 2026 that ground had still not been broken, and the developer did not respond to questions about the delay. A resort cannot be built in eleven months. The honest read: this is now a 2027 story at the earliest, whatever the official line says. Our Bahamas hotel guide covers what is actually open.
What does 2027 hold, and which name is already stale?
Kimpton Turks & Caicos is the headline volume play: 192 rooms, three pools and seven dining venues at the Bight on Providenciales, the largest of three IHG resorts being developed there by Molo Hotel Group, announced for 2027. Four Seasons Cayo Largo near Fajardo in Puerto Rico remains the region's great unknown: a 640-acre, villa-style, low-density project where more than half the rooms get plunge pools, and still no published opening date. Watch both; book neither yet.
The stale name is Rosewood Mandarina. It is not upcoming. The 140-key Riviera Nayarit resort opened May 8, 2025, has passed its first anniversary, and made Conde Nast Traveler's 2026 Hot List while mountaintop villas and added programming continue to roll out. Any openings list still carrying it is more than a year out of date.
When should you book a new hotel in this region?
Read the calendar against the storms. The St. Regis Costa Mujeres, Amanvari and, if October holds, the Andaz all open inside hurricane season, which is precisely when new properties discount hardest to seed their first reviews; the trade is real weather risk, and travel insurance is not optional money in this region between August and October. The properties already open tell the cleaner story: Park Hyatt Cabo del Sol and Alila Mayakoba both face their first full high season starting December 2026, and that is when their pricing power, and their flaws, will show. The rule we apply on the USA edition, the Europe edition and the Asia edition and the Middle East edition and the Africa and Indian Ocean edition holds here with extra force: re-verify any opening date four to six weeks before you commit, because this region's calendar has already moved four times this year. The world openings list and our ranked newly opened luxury hotels carry the wider picture.
