6 stunning undersea hotels

"Imagine telling your friends that you celebrated your love under the water in the world's only glass underwater chapel located five meters below the waves, surrounded by a vibrant coral reef!" crows the Rangali Islands website. Surely, it's what you've always imagined.

This luxe-to-the-max, six-star hotel is mostly above ground, spread over two separate islands that are connected by a 500-meter bridge. Below the surface, however, lies the fancy Ithaa Undersea Restaurant. Guests can simply dine at the Ithaa, but the Hilton-owned hotel is also happy to convert the restaurant into a wedding ceremony location for an untold -- and surely unbelievable -- cost. One option includes a celebration "in the heart of a stunning coral reef" in which the happy couple dives into the Indian Ocean (diving equipment costs extra, of course).
