Unimaginably cool. A little over five years ago, Conrad Maldives Rangali Island opened the very first undersea restaurant. To celebrate their anniversary, the restaurant offered guests the chance to not only eat under the sea, but sleep under it as well. The 12-seat restaurant, which sits 16 feet below sea level of the Indian Ocean, was converted into a private bedroom suite for two, complete with a private champagne dinner and breakfast in bed.
This would be cool but you'd have to b used to the smell of chlorine and b able to sleep outside all the time if dis wuz ur only bed and the bed could float off the pool in the middle of the night. Other than that, cool. JUST SAYIN
