My boyfriend and I recently did this excursion on our Disney Fantasy cruise. I'd have to say the best part about the experience was the crew. Josh, Fancy, and Mickey made us all totally comfortable while being very entertaining. They made sure we all had proper equipment and gave us lots of knowledge on the islands of Saint Thomas and Saint John. The snorkeling was beautiful, lots of fish and totally safe. On the ride back, we had a few glasses of champagne and rum punch - a perfect end to a great excursion. We will be returning to the island of Saint Thomas in October and we have our fingers crossed we will be able to get on the Champagne Cat once again!
