What's one way to show a little spontaneity in an un-adventurous vacation? How about a meeting under the sea. Ithaa, the world's first all-glass undersea restaurant at the Conrad Maldives Rangali Island, is celebrating its fifth anniversary by turning its underwater restaurant into a suite built for two.

The Maldives resort is offering guests the chance to spend the night under-water by turning the restaurant into an exclusive suite for two, complete with a private champagne dinner and breakfast in bed. (Caveat: Private in this sense means more underwater sea creatures and less humans.) Resting five meters (approximately 16 feet) below the Indian Ocean, the restaurant-turned-romance room is surrounded by a vibrant coral reef and encased in clear glass. Using aquarium technology, "Ithaa" meaning "pearl"in the Maldivian language of Divehi, was built to allow guests to enjoy the color, clarity and beauty of the Indian Ocean without getting their feet wet.

Diners at Ithaa Undersea Restaurant enjoy a set-menu of 23 different dishes over four courses. The restaurant is adults-only for dinner (children can join for lunch) and it only seats 12 people.

The cost of this little luxury? $320 per person for dinner. Want to spend the night? The price is available upon request, depending on your dates of travel.
