I posted for some excursion help for my last cruise in November and received great advice, so I'm back again. This time we are going to the Eastern Caribbean on 2/9 so we're looking to snorkel in St. Thomas and St. Martin. From what I've read, Coki beach is the place in St. Thomas and Dawn Beach in St. Martin. There will be three of us and we want to do this on our own as our experience is its cheaper. What I would like to know is first, are these the right places to snorkel and second, what is the expected cab fare to get to the beaches and back? Also, can you rent snorkel gear at both of these places? If so, do you know the rental price? Any assistance you can provide is greatly appreciated.
