These 5 Underwater Resorts Will Literally Put You Under the Sea

Nestled against the largest aquarium in the world, five-star hotel Resort World offers 11 two-story suites that feature an open-air top level — complete with an outdoor patio and Jacuzzi — and a totally submerged lower level with views directly into the aquarium. Although the suites do come equipped with all the modern luxuries, who needs cable when you can watch more than 40,000 marine fishes swim by your window?

Themed around the mythical lost city of Atlantis, this swanky Dubai resort pulls out all the stops for lovers of both luxury and underwater adventure. Guests can spend the day at the adjacent Aquaventure water park, then cozy up in one of the signature underwater suites, where you'll be spoiled with breathtaking floor-to-ceiling windows that peer directly into the lagoon and 24/7 butler service.

While the villas at the stunning Maldives retreat Conrad Rengali Island are perched over the Indian Ocean, the resort is famous for its completely submerged five-star restaurant. Feast on a chef-curated six-course dinner while taking in panoramic views of the vibrant marine life around the coral reef. The word is that the restaurant can even be turned into a private overnight suite (for quite a few pretty pennies, of course).

Spend a night with squid, octopus, and other unusual marine life in this African resort's famous floating island, a three-story room with a sunken bedroom that offers 360-degree views of vibrant ocean life. Head above sea level at night to take in incredible vistas of the stars and the Milky Way on your private deck, as the room is stationed more than 800 feet from shore and free of light pollution.

Touted as the world's first affordable undersea luxury hotel, Key West-based resort Planet Ocean Underwater takes its guests three stories below sea level for an incredible overnight experience amid bountiful ocean life. The goal of the project is to fund worldwide coral reef restoration, and as a result, the resort will continue to move to different spots around the globe, from Cuba to Sri Lanka.
