We usually tentatively plan several trips, but if you are staying near a nice beach, ( you didn't say where you were staying) we end up spending more days at that beach than traveling. Anquilla is gorgeous, and well worth the time spent in travel, I didn't feel the same about Pinel, though others love it. I would suggest spending more time on St. Martin and at the beach near where you are staying. You didn't list Mullet Bay - if you like beaches, it is one of our favorites in SXM and you might want to add it to your list. Have a great trip.
