I agree with the above. My favorite thing is to circle the island and stop at various places, although I hope to do the shipwreck snorkel sometime. One of my favorite spots there is Margot, on the French side. Beautiful little village with a fort overlooking the bay. Another good excursion is horseback riding. I booked it independent of the cruise line (don't recall the name, Lucky stables maybe? -- on the Dutch side) and we had a great time.
