FLORIDA KEYS — Perhaps because the southernmost islands in the continental United States have never experienced a snowy white Christmas, businesses and organizations in the subtropical Florida Keys are extraordinarily enthusiastic about showing their holiday spirit.

From Key Largo to Key West, the calendar is packed with events designed to spread holiday cheer — including a trio of festive lighted boat parades featuring vessels whose decorations range from traditional greenery to offbeat salutes to the season.

Listed here are some holiday highlights, all spiced with an individualistic Florida Keys flair.

Now Through Tuesday, Dec. 22 Holiday Photos with Santini (or another dolphin) at Dolphin Research Center (Marathon) At Dolphin Research Center, mile marker (MM) 59 bayside on Grassy Key, visitors who participate in the Meet the Dolphin program also can pose with the dolphins for a holiday photo. Visitors can select props such as Santa hats, reindeer antlers, and holiday wreaths to use while posing, and DRC’s experienced photographers will shoot the pictures using high-resolution digital cameras. Meet the Dolphin gives guests an opportunity to go onto the facility’s floating dock to give backrubs and share a “flippershake” with a dolphin. The program is offered several times each day on a walk-in basis and costs $25 per person in addition to general admission prices. The photos can be supplied on CD for $25 (including all members of the family), or as prints. Print prices vary depending on number ordered. Contact: (305) 289-1121.
