Isn't Castaway at Great Bay? We took a taxi to Orient Beach, on the French side. We asked for Coco beach club but he dropped us off in front of Kontiki. Looked very good, so we walked in. Nice lounges and clean facilities. About$10 more for lounges than most places, but a little upscale. Good drinks and food, too. At your lounge or at the restaurant and bar. I think any of the beach clubs on Orient Beach are fine for a day. When we left, there was a taxi right there. Or the bar will call for you. $25 each way from Phillipsburg.. Per car, not per person. Much less crowded than Great Bay, if that's important for you.
