World's Most Unusual Hotels

Jules’ Undersea Lodge, Florida

What It Is: A 70’s-era research lab turned two-bedroom capsule in Key Largo that can accommodate six guests on the floor of the Gulf of Mexico.

The Experience: Guests scuba dive to this unique unit, located 21 feet below the surface. Once inside the 600-square-foot capsule, there are all the accoutrements of a regular hotel, including a spacious living room with TV and stereo and a dining area. But that’s where the similarities end. In the pair of bedrooms, the lodge makes full use of its location, with 42-inch circular windows that offer views of passing sea life, including barracuda and angelfish.
