Mountain views and ocean vistas are so last decade. Today, hotels under the sea are all the rage. Fall asleep counting fish and stick around for feeding time; these rooms let you see the underwater kingdom like never before. On your next vacation, venture below the surface at one of these five underwater hotels, and you’ll soon discover that the world is your oyster.

Underwater Suites at Atlantis The Palm, Dubai

Live like a mermaid under the sea at Atlantis The Palm. The Poseidon and Neptune Underwater Suites take you below the surface, but you don’t need to your fins to enjoy the view. Draw back the bedroom curtains, and you’ll find yourself submerged in an underwater world filled with 65,000 marine animals. The luxe suite’s floor-to-ceiling windows overlook the Ambassador Lagoon and the mythical ruins of Atlantis, where schools of fish gather and sting rays soar through the water.

Ocean Suites at Sentosa, Singapore

Get ready for a whale of a time in the Ocean Suites at Sentosa. OK, you won’t see a whale, but you will see a shark—maybe even two! At this underwater suite, set your sights on more than 40,000 sea animals that live in one of the world’s biggest aquariums. The best hour to view? Feeding time, of course. From the comfort of your bedroom, watch as swarms of hungry fish flock to the scuba divers’ handouts.

The Underwater Room at Manta Resort, Zanzibar

The Underwater Room at Manta Resort is the real deal. Instead of overlooking an aquarium, this below-the-surface room features 360-degree views of the deep blue sea. The floating hotel is like your own private island, with a sun deck on top and a bedroom beneath the water. Head down into the viewing room and enjoy the show: Octopuses suction themselves to the windows, while reef fish peer inside.
