Key West.

You forgot to mention the main reason to go to Key West.

Great sailing and snorkeling!! The best trip of all is on 65-foot schooner REEF CHIEF [link removed by admin] 305 292 1345. Groups can charter the entire schooner for private sails or joing half day trips.Totally laid back, not the commercial rush rush cattle boat catamaran. Four hours of killer fun. Two hours of great sailing, and two hours of excellent coral reef snorkeling at an off the beaten track coral reef. Dolphins, mermaids, sea birds. What you dream of when you dream of PARADISE!
