Cayman Islands
Here is fun in the sun you can take all the way to the hundreds of banks in this offshore tax haven. Comprising three islands and a population just over 30,000, the Cayman Islands were the setting for the hit Tom Cruise film: The Firm. Diving is big in the Caymans. In fact, treasure hunter and expert diver Herbert Humphreys is headquartered in the island capital of George Town.
