The Reethi Rah Resort in the Maldives might have more than 50 pools on the property. But this adults-only lap pool is especially lovely. It's kind of hard to tell where the pool ends and where the ocean begins.
It's a mega yacht. With a built-in lagoon. Called the Tropical Island Yacht, this giant 100 million dollar boat from Yacht Island Designs features a volcano waterfall, which flows as a stream into a tide pool, then into a lagoon pool.
