Sounds like a great time was had by all!! I will recommend with a group that big. Think about going out on the Rhino Safari riders and snorkel trip to Creole rock from Pineapple Pete's marina. Leo would have you has a privet group!! It's a blast!! We gone out more than a few times, always a great time!! As a privet group you can omit the snorkeling if you want, IMHO, do it at least once, bring camera's! BTW, my wife "Fabila" did it for the first time this past November and had a BLAST!!
