Grand Hotel Cancun Formerly the Ritz-Carlton Cancun, this luxury Cancun resort was reborn this summer as the Grand Hotel Cancun. Don’t expect the 363-room hotel’s legendary service to fall off, however: the Grand Hotel Cancun is managed by Kempinski, another five-star luxury hotel brand. Notable amenities include a tennis center and a luxury spa offering Mayan inspired treatments. And it will soon relaunch with the Kempinski name, too.
