The yacht race excursion is fun. The shopping is really touristy and everywhere. Be aware of asking for a "special design" on a t-shirt. If they make a shirt for you it can cost a bundle. Stick with those already made. Most shops are legitimate but there are some that like to rip off tourists. Of course, no trip to Key West would be complete without a pilgrimage to Margaritaville for a cheeseburger and margarita (actually very good).
