Has anyone done this excursion while in St. Maarten? DH and I are planning on doing this on our Nov. cruise and were wondering if we could use our own snorkling equipment. The PassPorter says that the snorkle equipment is provided but we have "dry" snorkles, which I would definetly prefer to use. I also get the "willies" thinking about using a snorkle that has been used by other people and "sanitized". Maybe we could just bring our snorkles and masks and use their fins. It would be less to have to carry. Any ideas about this?
