We did our own tour last December using cabs. If you have kids I would HIGHLY recommend Le Gallion Beach. It's just south of Orient but is more protected so calm smooth waters, no seaweed, and very few people selling stuff. Loved it! We then took a cab to Maho beach. While we had enough time would caution as there is one main road it can get busy with traffic. Also Maho was crazy busy so it was nice to be sevto hop out of a cab and not try to find parking. Hope you have a great day there!
