Shore excursions in the caribbean? Why would I pay thirty dollars to go to the beach?

well....other than sucking revenue from people excursions thru the ship, especially your first time, unless you have been to these particular islands, does give you the security of knowing the boat wont leave without you, that you will be in a safe area, and that your transportation will actually take you where you want to go. I have been on 7 cruises and although I don't always book my excursions thru the ship i do deal with reputable companies. If you snorkel, its nice to know where and who you are going with. (St Thomas...Castaway girl does excellent snorkel trips), In St Maarten you can probably go to the beach on your own, be prepared, many are topless. Have fun and keep an open mind
