If you're looking to go beyond ocean views and sandy beaches, then staying in an underwater hotel may be right up your alley. There are very few places in the world where you have to use scuba gear before settling down for the night, but at the Jules' Undersea Lodge in Key Largo, you better be ready to dive into the deep. This underwater research habitat is also available for everyday people who want to sleep in the ocean. Overnight stays start at $375 per person.
