I was thinking Pinel Island.....we've not had a lot of luck in seeing very many fish at the shipwrecks, most are too far down. Also, we like the idea of being able to explore the island, etc.
Then we decided after returning from Pinel, we'd taxi to Marigot to look around, see Ft St. Louis (and be able to say we were on both sides of St Maarten) and still have time to look around Phillipsburg before re-boarding.
I've read in my travel guides (for scuba & snorkel) about most of the Eastern's sites and I use that to compare to Disney's descriptions....Pinel sounds like the best.
As for St Thomas, we're going on our own to St John, Trunk Bay Beach. Our second choice is to look around Charlotte Amalie, maybe do the tramway, or a taxi to Bolongo Bay Beach Club. Our 3rd choice would be Coral World, which we would do by taxi on our own. I don't like the idea of going on a bus, on their schedule, and it's too much money that way. St Thomas is the easiest place to "go it on your own". The ferries and taxi's are right there at the port...it is their livelihood, so you're safe...
There is a public bus to Coral World, $5 pp, much cheaper than Disney. (Sorry,
