Has anyone been left at the beach at St Thomas, Taxi's not getting back to pick you up?
Nope, and Coki is the smaller, further out beach of the two. It has clearer water and is more used by the locals. We had a guy who was more than ready to take care of our needs and when it came time to leave, he had a taxi there and got everyone together. There were about 11 of us in total and we all fit in one vehicle and all went back together. The other beach where the tourists go costs $10 to get in, is bigger, but not as good for snokeling. Megan's Beach I think is the name of the other beach and it was about $8 pp from town for the taxi.
In fact we were told later that had we asked, the taxi who brought us out would have been more than glad to come back for us and probably was a little upset about not being asked to come back for us. They either really want that taxi fare or they are really trying to take care of you.
