There's a cheeky sense of fun across Key West, from the nightly sunset celebration at Mallory Square (keep an eye out for the acrobatic cats) to the colorful bungalows of Bahama Village. Add in mangrove reefs rich with marine life, museums with pirate treasure, and a great dining scene, and you have all the ingredients for a fantastic port call. Cruise ships dock near Mallory Square, within easy walking distance of the sights and sounds.
