St.Thomas Catamaran Sail

Hello All

My family of 4 is going to the Eastern Caribbean on the Fantasy in November. We are considering the Catamaran Sail and Snorkel to the Private Beach (ST 56) port excursion in St. Thomas. Has anyone done this one? Any reviews, advice, tips? Thanks!

I did on Carnival and the Champagne Cat. Loved it!

We took the Castaway Girl Catamaran over to Shipwreck Cove - loved it! Had the most wonderful time; the crew was fun and informative. I had never snorkeled before, and now I can't wait to go back!
