i know tons of people have been to Key West. what would you reccomend to do while down there? what companies are the best to use for snorkeling?

Floridays for snorkeling. They dock at the Hyatt on Front Street and limit the number of passengers to around 20.

Take a Conch Train tour to get the history of the island and where everything is. You will understand more about Key West doing this.
Go to: Sunset Celebration @ Mallory Square & watch the street performers; Hemingway house; Little White House; Mel Fisher's Museum, stroll around Old Town to see the beautiful Victorian homes and architecture. Take a bicycle tour from the Moped Hospital. Check out the art Galleries on Duval, wander around the walkways from The Turtle Krawls to downtown.
Eat at: El Siboney on Margaret St. on the Atlantic side. Half Raw Bar at the end of Margaret St. on the Gulf side. Good pasta @ Mangia Mangia on Margaret St. (up from the Raw Bar). Enjoy.

Kelly's is a great place to eat dinner. They have a beautiful courtyard where there is plenty of shade and the food was wonderful. Say hi to Stephanie - a great waitress!!

Drink beer at Boar's Head and Sloppy Joe's as part of an all-night "Duval Crawl."

For authentic Cuban food, check out Joe's Cantina on White Street.
