The St. Regis Costa Mujeres Resort Cancun has just opened, as the brand’s second property in the Cancun area. As you’d expect, it’s pricey, but for some people, it will definitely prove to be an easy and luxurious getaway.
Details of the 213-key St. Regis Costa Mujeres Cancun
The St. Regis Costa Mujeres Resort Cancun has opened as of late June 2026. This property is located in Costa Mujeres (as the name suggests), around 20 minutes by car north of Cancun. For context, there’s also the St. Regis Kanai Riviera Maya, roughly 40 minutes by car south of Cancun (so the two resorts are around an hour apart).
The resort is located on a 3.5-hectare site along the Costa Mujeres beach, which is not particularly wide, unfortunately. However, it is just a short boat ride from Isla Mujeres, which many people will appreciate. The resort features a total of 213 accommodations, including 163 guest rooms and 50 suites.
As you’d expect, the resort has lots of amenities, from several pools, to a full service spa, to a gym and kids club, to a variety of restaurants and bars.
Dining options include Costa Coral (an all-day Mexican restaurant), Fish Market (a Caribbean restaurant open for lunch), Palmare Grill (a seafood restaurant open for lunch), Shami (an Asian fusion restaurant open for dinner), and the St. Regis Bar.
This resort was first announced in late 2022, with a planned early 2025 opening. Now it’s finally open as of mid 2026 — while that’s a substantial delay, we’ve seen worse.
St. Regis Costa Mujeres Cancun rates & points requirements
With the St. Regis Costa Mujeres Cancun now open bookable, what are rates like?
Entry level rates currently start at just over $660 per night, though that’s before Mexico’s high taxes and service charges, which add 30%+ to the base rate.
However, there’s quite a bit of seasonal variation, and in peak season (winter), rates start at closer to $1,000 per night.
If you’re going to book a cash stay here, I’d recommend doing so through the Marriott STARS program, to receive perks like free breakfast, a $100 resort credit, a room upgrade, and more. Ford and his team can help with these requests, and can be reached at [email protected].
For those looking to redeem Marriott points, I see rates starting between 104,000 and 126,000 Bonvoy points per night. Keep in mind that you can receive a fifth night free on award redemptions, which improves the value somewhat.
Based on my valuation of 0.7 cents per Bonvoy point, I’d say the math is generally pretty breakeven when it comes to paying cash vs. redeeming points, especially after factoring in taxes & fees. You definitely get more value with your points in peak season, though.
Bottom line
The St. Regis Costa Mujeres is now open, as the St. Regis brand’s second property in the Cancun area. It’s interesting to see the growth of more non all-inclusive luxury properties in the region beyond Mayakoba. I’m curious to see how this resort looks in real life.
