While you’re in Florida visiting the best beaches in America, take a detour to Key West, home of the Planet Ocean Underwater Hotel. Located 30 feet below the surface, the hotel’s 12 bedrooms are accessible via a glass elevator and provide a panoramic view of aquatic life. A marine biologist will accompany guests to explain the marine life around them. But here’s the catch: Only 90 groups (with 12 couples each) will be able to stay at the Key West location once it officially opens. After that, the hotel will travel to other locations—Okinawa, Japan, Singapore, and Thailand are listed on the hotel’s website—to bring the experience to other citizens of the world. Better make your reservation fast for this underwater hotel.
