I was just looking at the excursions, as I got reminded by my TA yesterday that I can book 90 days out. I have one question for those of you who have been to CC recently, if I bring my own mask and snorkle (rented snorkels, ewwwww), will I be required to rent a PFD (vest) or can I just hop on in with out it? If I decide to go to the "Snorkling Lagoon", will they be on the lookout for non vest wearers? I honestly see that the vest is a good thing, and I don't mind wearing one, but just curious. And as I don't dive under, I really don't want to get fins.
