We went on the excursions to Megan's bay and Paradise Point on St. Thomas. That was for our first visit..and we all really enjoyed it. The last time we visited St. Thomas we took an excursion over to St. John's Trunk Bay...that was a lot of fun as well.
On St Marteen...we took an island tour so we could see both the french and the dutch sides. It's a great way to see the Island and you have a bit of a chance to shop on both sides. Don't miss the Belgium Chocolates!
All three of these excursions were ones Carnival offered.
