About weddings in Key Biscayne
Key Biscayne is an island you reach by toll bridge, with the Atlantic on one side and Biscayne Bay on the other. The Cape Florida Lighthouse, standing since 1825, is the oldest structure in South Florida and one of the few genuinely historic backdrops on a Florida beach. You have real choices here: the Ritz-Carlton, the Grand Bay Club, Bill Baggs Cape Florida State Park and the Key Biscayne Yacht Club. Beach, park and marina weddings all work. Barns and urban ballrooms don't. A venue costs about $12,720, food is $138 a head, and an open bar adds $60. Expect about $52,100 for 120 guests. One logistics note: the Rickenbacker Causeway is a toll bridge, and it's the only way on or off the island. Tell your guests.
