a full-day trip outta Key West to a place called the Dry Tortugas is alot of fun. Good history of an old fort, nice picture taking and snorkling.
there are alot of great bars in Key West, and alot of good live music. But make sure to go to the Garden of Eden. Its the top floor of a bar (whose name i cannot recall), is open air, and clothing is optional. Just ask where it is, you won't be let down!!
If you are looking for a good resturant in Key West, look up BLue Haven in the phone book, and get the lobster bisque.
