Hi - CM staff (which are amazing so far!) suggested we bing rafts and simply blow them up there. I was thinking about bringing our own snorkeling sets so we could use them any time - worth it? What about towels? We are packing super light - should we leave room for souvenirs? Wasn't sure about bringing iPad or laptop - definitely need some form of Internet. Are the electrical plugs American standard or o we need converters? Any other advice is greatly appreciated. We are bringing sunscreen/bug spray.
