How we tracked and verified this
This is a freshness tracker, not a quality ranking: open resorts are listed first, with the clear line between open and bookable now and still to come. Every date is tied to reporting from outlets including The Points Guy, Caribbean Journal and One Mile at a Time, plus the brand's own listings, and cross-checked against current booking availability. We mark expected dates as expected and never present an unopened hotel as bookable. Because this is a brand pipeline that moves, treat any future date as provisional and confirm directly before planning a trip around it.
Recently opened
1
Ummahat Island, Saudi Arabia
The St. Regis Red Sea Resort
Opened 2024 · 90 overwater and beach villas
Why it leads: the most striking recent St. Regis, and a sign of where the brand is heading. Set on Ummahat Island within Saudi Arabia's Red Sea Global project, it has 90 overwater and beachfront villas, each with its own pool, over clear water and coral. It is the rare St. Regis that competes directly with the Maldives on setting, with the newness and scale of Saudi Arabia's pioneering Red Sea destination behind it.
Getting there: fly into the Red Sea International Airport, then transfer to the island by boat or seaplane. Who it's for: travelers who want an overwater-villa escape somewhere genuinely new.
Honest note: this is a remote, brand-new destination still building its surrounding infrastructure and flight links, so research transfers and what is fully open before you commit, and weigh it against the established Maldives resorts it is priced against.

Cap Cana, Dominican Republic
The St. Regis Cap Cana Resort
Opened 1 May 2025 · 200 rooms and suites
Why it's here: the brand's newest open resort, welcoming its first guests on 1 May 2025 in the gated Cap Cana enclave near Punta Cana. It has 200 rooms and suites, four pools, beach access, a 13-room spa and full St. Regis butler service. Its real point of difference is the format: it is one of the first ultra-luxury European Plan, room-only rather than all-inclusive, resorts in an area dominated by all-inclusives.
Getting there: about a 15-minute drive from Punta Cana International Airport, one of the easiest-to-reach openings on this list. Who it's for: travelers who want Caribbean beach luxury without the all-inclusive buffet model.
Honest note: the European Plan means dining is paid separately, so the headline rate is not the whole cost, budget for meals, which run high. As a 2025 opening it may still be settling in.

Longboat Key, Florida, USA
The St. Regis Longboat Key Resort
Opened 2024 · Gulf-coast beach and spa
Why it's here: the brand's Gulf-coast resort, opened in 2024 on a barrier island near Sarasota. It pairs an 800-foot private white-sand beach with a large oceanfront spa and a long winding pool-river, a full-scale beach resort rather than a city St. Regis, and one of the brand's most significant recent US openings.
Getting there: fly into Sarasota-Bradenton (SRQ), then a short drive onto Longboat Key, an easy domestic option. Who it's for: US travelers who want a St. Regis beach resort without leaving the country.
Honest note: Gulf-coast Florida has a defined high season and a summer storm season, so timing matters, and rates at the top of season are firmly luxury-tier.

Riyadh, Saudi Arabia
The St. Regis Riyadh
Opened 2023 · Marriott's 500th luxury hotel
Why it's here: the brand's Saudi capital debut, opened in 2023 in the Diplomatic Quarter and marked as Marriott's 500th luxury property worldwide. It is a smaller, boutique-style city hotel with 83 rooms and 21 suites, including a two-bedroom Royal Suite, aimed at diplomats, business travelers and the capital's fast-growing luxury market.
Getting there: roughly 35 minutes from King Khalid International Airport, in the leafy Diplomatic Quarter. Who it's for: business and government travelers who want a discreet city base.
Honest note: this is a compact city hotel, not a resort, so set expectations accordingly. It reflects the brand's heavy bet on Saudi Arabia, useful context when you see how many St. Regis announcements now come from the Kingdom.

Riviera Maya, Mexico
The St. Regis Kanai Resort
Opened 2023 · beside the Sian Ka'an reserve
Why it's here: the slightly older but still-recent Riviera Maya resort, opened in early 2023 next to the 620-acre Sian Ka'an nature reserve, a short drive from both Cancun and Playa del Carmen. With 124 rooms and 19 suites, it brought the St. Regis name to one of Mexico's most popular luxury coasts, alongside the adjacent Riviera Maya EDITION.
Getting there: about an hour from Cancun International Airport. Who it's for: travelers who want a polished Riviera Maya base near nature, away from the Cancun strip.
Honest note: the Riviera Maya is busy and developing fast, and regional seaweed (sargassum) can affect beaches seasonally, worth checking for your dates.

Costa Mujeres, Cancun, Mexico
The St. Regis Costa Mujeres Resort
Opening 25 June 2026 · reservations open
Why it matters: the brand's headline 2026 opening and its second resort in the Cancun area after Kanai. Opening on 25 June 2026 with 163 rooms and suites in a soft palette of blonde woods and earthy tones, The St. Regis Costa Mujeres is already accepting reservations, on the calm, quieter coast north of Cancun.
Getting there: roughly 40 minutes north of Cancun International Airport, in the growing Costa Mujeres resort zone. Who it's for: travelers who want a brand-new St. Regis on a quieter stretch near Cancun.
Honest note: at the time of writing it has not yet opened, so treat the date as the brand's plan, not a guarantee, and expect a genuine settling-in period in the first weeks. Confirm what is fully operational, restaurants, spa, pools, for early stays.

What the new openings tell you about St. Regis
Two patterns are clear. First, the brand has tilted hard toward resorts over city hotels: the splashiest recent openings are a Red Sea island, a Caribbean beach resort, a Florida barrier island and a Mexican coast, with Riyadh the lone pure city debut. If your image of St. Regis is the marble grandeur of the New York original, the brand's growth is now mostly sun-and-sea.
Second, the geography leans heavily toward Saudi Arabia and the Americas' resort coasts. The honest caveat for anyone using a page like this: separate open hotels from announcements. St. Regis, like its peers, also lends its name to branded residences and projects that are years from a bookable room, so check that a much-hyped "new St. Regis" is actually a hotel you can stay in before you plan around it.
Frequently asked questions
- What is the newest St. Regis hotel?
- The freshest St. Regis to open is The St. Regis Cap Cana Resort in the Dominican Republic, which welcomed its first guests on 1 May 2025 with 200 rooms and suites. The next to open is The St. Regis Costa Mujeres Resort near Cancun, taking reservations for stays from 25 June 2026. Both follow recent debuts in the Red Sea, Riyadh and Florida.
- What new St. Regis hotels are opening in 2026?
- The headline 2026 St. Regis opening is The St. Regis Costa Mujeres Resort near Cancun, opening on 25 June 2026 with 163 rooms and suites and already accepting reservations. It is the brand's second resort in the Cancun area after Kanai. Beyond it, St. Regis has a deep pipeline weighted toward Saudi Arabia and resort destinations, though firm dates beyond 2026 tend to move.
- Where is the new St. Regis in Saudi Arabia?
- There are two. The St. Regis Red Sea Resort sits on Ummahat Island in the Red Sea Global project, with 90 overwater and beachfront villas reached by boat or seaplane. The St. Regis Riyadh, which opened in 2023 as Marriott's 500th luxury hotel, is a smaller 83-room city hotel in the Diplomatic Quarter. Saudi Arabia is a major focus of the brand's growth.
- Is the St. Regis Cap Cana open and bookable?
- Yes. The St. Regis Cap Cana Resort opened on 1 May 2025 in the Dominican Republic and is open and bookable, with 200 rooms and suites, four pools, a 13-room spa and St. Regis butler service. It is notable as one of the first ultra-luxury European Plan, room-only rather than all-inclusive, resorts in the Punta Cana area.
- How reliable are these St. Regis opening dates?
- The dates for hotels already open are firm, and we list those as bookable. Future openings are less certain: luxury brands announce ambitious pipelines, and dates for properties not yet open commonly slip by months. We mark The St. Regis Costa Mujeres as opening 25 June 2026 because reservations are live, but always confirm directly before planning a trip around any unopened hotel.
- How many St. Regis hotels are there?
- St. Regis operates more than 50 hotels and resorts worldwide and has been expanding quickly, with Marriott targeting a substantially larger portfolio. Growth is concentrated in resort destinations and the Middle East, especially Saudi Arabia, alongside a steady stream of branded residences that carry the St. Regis name without always adding a bookable hotel.
