My favorite excursion of all was the Golden Eagle Out Island Sail in St. Maarten, as has been mentioned in the previous posting. I will be signing up for that excursion again when I cruise in April. For St. Thomas (if you're not into the shopping), I really enjoyed the Champagne Catamarran to St. John. For St. Kitts-Sailaway to Nevis was fantastic. The snorkeling was not good, but the catamarran sail was beautiful and we were taken to a secluded beach, where we had a barbecue and open bar. That is a great excursion. If it is still offered in Barbados, go on the Mount Gay Rum Factory/Pub Hop. The rum factory is not that impressive but we had the BEST time. Anigua-anything on the water-the water is stunning. Hope this helps. Have fun.
