There were several good ones to choose from, however I think a lot of people did the Canopy Tour of the rainforest. There was also a Countryside Beach Getaway (which would have been my choice) and there was an island tour called East of Eden for those that wanted a less active tour. Mostly, we have chosen the snorkeling tours and they have been great. The best snorkeling that we experienced was in St. Kitts. We saw stingrays, turtles, and loads of colorful fish and coral. The crew on the catamaran were also fantastic. The catamaran was called "Irie Lime" which they told us translated into "Good Party" and it was. :) We did not snorkel in Bonnaire, however we were told that it was quite spectacular as well. We did the ship's snorkeling tours in Aruba, Curacao, and St. Kitts and they each had their own particular charm etc. My favorite though was St. Kitts.
