I agree, Maegen's is beautiful, no loungers though- there are picnic tables there, or you can sit on the towels you bring. They rent kayaks there if you like that. It is very peaceful. Sapphire Beach is a bit further out, but they rent loungers, have a cafe. I think
DCL has an excursion there.
Last time we were at Maegans, we went over until noon, went back to the ship, ate lunch & went back to town to shop. You could bring a lunch from the ship with you if you wanted to stay there, but there is a concession stand there if you don't.
On St. Martin, Orient Beach is beautiful. DCL does a nice excursion there with loungers & lunch on the family side of the beach. It's a bit more expensive than renting a car, or taxi, but it's easy... The french side of St. Martin is clothing optional. You see some topless on the family side, but not too bad- very euro..
You want to stay away from Club Orient, which is completely nude. The DCL excursion does not take you on that side of the beach. Dawn beach is nice too, not as nice as Orient, but a 10 min. taxi ride. I've never been to Great Bay Beach, as we like the French side- much prettier.
St. John is beautiful- National Park as well. The DCL excursion is a herd like atmosphere. Going on your own is better, but as the Disneykins said, you need to watch the return ferry to insure you get back to the ship on time. You don't want to miss the ship!
