Yes, at two of the 12 hotels. Day passes run from MX$700 at Hive Cancun to USD $120 per person at Royalton Chic Cancún.
Hive Cancun is our value pick, but its rooftop minipool is for select Master Suite guests, so the pass covers the hotel's facilities. No pass hotel publishes a child ticket. Royalton Chic Cancún is our adults-only pick, 18+, with a meal plan and open bar included.
The short version
Cheapest
Hive CancunMX$700 pass, but the suite rooftop minipool isn't included.
Non-guests can buy a pass from USD $120, with a meal plan and open bar included.
The pool
The pool runs along the Level 18 rooftop of Royalton Chic, on Blvd. Kukulcan Km 9.7 in Punta Cancun, 18 stories above the city. The hotel describes an adults-only day-party pool with cabanas and panoramic views of the Cancun shoreline. The catch is the price: passes start at USD $120 and the deck is 18+ only.
The day pass
From USD $120 per person. It includes a meal plan and standard open bar.
Insider tip: Work out the cost per drink before you buy: the USD $120 pass covers a meal plan and standard open bar, so it suits a long stay on the deck.
The minipool belongs to the suite, so only the suite's guests swim in it.
The pool
Hive Cancun, on Av Huayacán in Supermanzana 336, puts its rooftop pool on the private terrace of its Master Suites. The minipool belongs to the suite, so only the suite's guests swim in it. The hotel gives no pool size, and the view is open city.
The day pass
The day pass costs MX$700 and gives access to the facilities and premium services, with no overnight stay. The hotel doesn't say it includes the suite rooftop minipool.
Insider tip: Ask the hotel which Master Suite types have the rooftop minipool before you book: it is the Two Beds and King suites.
Guests only: no day pass
The other 10 hotels publish no day pass. None says it opens a rooftop bar to the public, so treat their pools as guest perks.
