I've been here before but never taken an organized tour. If you just like to relax, take a taxi down to 7 mile beach and grab your own private spot. For those that like shopping, there are many tourist stores. However, I do recommend a Stingray/snorkeling tour. Even with beginner to moderate swimmers, lightweight preservers are mandatory so all are safe. You will see many friendly stingray and they seem to know there is no danger to them. They are free to come and go off this sandbar and always manage to grab some squid chum. To my knowlege, there has never been any bad incident. They welcomed people and didn't mind being touched. Those that didn't want to be touched just cruised on by you.
