I agree about Bernard’s Tours. I took one some years ago and am going on the same one again this fall. You get a good tour of the island (both the Dutch and the French sides), beach time, some beautiful vistas, a visit to a lizard farm (that was fascinating), a stop at Maho Beach to watch the planes fly in low overhead, some time in the a French town of Marigot to eat or shop, and so on. My husband and I really enjoyed it.
