Dubai is a place of superlatives, and this hotel lives up to its location. The world's largest jellyfish pool welcomes guests in the lobby; leisure fun reaches new dimensions in the Aquaventure Waterpark with 105 attractions and in the infinity pool on the 22nd floor. There are also 17 world-class restaurants - eight of which are run by celebrity chefs - and a 3,000 m2 wellness centre. The split-level penthouse "Royal Mansion" is one of the most exclusive accommodations in the city. www.atlantis.com
