My DH would like to snorkel on Castaway Cay..is he allowed to bring his own gear or does he need to rent those from Disney? ( I am guessing he does since he has to also wear a vest which is in the package?) Do you have to pre choose your Castaway Cay rental items or can you choose once you get there? In Key West, has anyone taken the Presidents, Pirates and Pioneers tour? I'd like to try that Key Lime pie on a stick that was on Food Network..I saw it mentioned here but can't remember where to get it..Any advice on these two ports?
