Sloppy Joes bar after a sunburn from too much snorkeling, will help to ease the pain. The pier at sunset has every hippie not in San Fran out there and some of them are pretty talented jugulars, mimes, musicians, dancers etc.,
Get some fried conch while you are there. It can be prepared so that its tender and tasty. Keep an eye out for sharks, seem like this is the time of year for Florida to have shark attacks too...
