We just took the Eastern in April with DDs--3 and 5 and our infant son. The girls loved Coral World in St. Thomas. We went on our own. We took a taxi to a beach and spent the morning, had lunch, and then went to Coral World. In St. Maarten, we skipped the Butterfly Farm because we have one near our home and just went to a nearby beach. It was nearly deserted and the girls played and took walks and had such a great time. We left around 1:30 or so and took advantage of the ship in the afternoon. The pools were deserted so the girls swam in the Mickey and Goofy pools, had ice cream etc. We did everything on our own because the Disney excursions often offered an island tour etc. which they wouldn't have enjoyed. Good luck! We can't wait to go back!
