Fantasy Fest in Key West is a yearly celebration, occurring each year in late October, that has been compared to events like Mardi Gras in New Orleans. This very "adult" festival features a parade, the crowning of the Conch King, and many other interesting events. If you have a very open mind and are looking for a ten day party then you must go to Key West for the annual Fantasy Fest celebration. Just make sure you get your Key West hotel reservations far in advance because the population of the island triples during the party.
