Top 10 Underwater Travel Experiences

Poseidon Undersea Resort

Everyone wants a water-view room while on vacation, but what if you want to see what's going on under the waves? Almost 71 percent of the earth is covered in water, which means there is a lot to see below the surface. Developers unsatisfied with the options above ground are now making a splash with underwater hotels, restaurants, and spas. If you do want the full experience, slip on some flippers and goggles and visit the breathtaking sculpture gardens and Roman ruins that hide under water -- you may even see the answer to one of the history's greatest mysteries.
