Which beach excursion?



We are going on the Explorer of the Seas on March 4th. We need to book our excursions asap, but I can't decide which to do. Any advice??

We are looking at St. Martin Beach Rendezvous, St. Maarten Sensation & Beach Break, Divi Little Bay Beach Experience or a tour with Bernard. These are all excursions through RCI except for Bernard. The only worry I have is being rushed around. I really want to be able to go to the beach for the day and go back to the ship when I want.

Most of these include lunch, couple drinks, and a beach chair.
