I'm right there with you! Yes, I think your 9 year old would have to have a parent to go parasailing, so you are all set on that. I'm wondering about the Banana Boat ride. If my 8 year old son fell off, he wouldn't be frightened, but he wouldn't be able to traverse the ocean currents either to get back to shore. As long as he was in a life jacket he would be fine bobbing until he climbed back on, I think. Still not sure on that one! I think we are doing St. John on our own and have not made up my mind for sure on St. Marteen. I'm leaning toward doing it on our own as well. Then we can go to whatever beach looks lovely and uncrowded that day.
Are you figuring 9/2 is the 60 day mark? I think it is Labor Day, and I wondered if the office would even be open for reservations.
