My family will be on the Emerald Princess in November, stopping in Antigua. We would like to take the Sail, Snorkel, & Beach tour (ANU-810) offered from Princess Cruises. It's a catamaran sail to a nearby barrier reef for a snorkeling, followed by fun in the sun on a beautiful beach. Has anyone taken this trip from Princess Cruises before and can give me an idea of if trip has value for the money? Does anyone know the name of the beach that the catamaran goes to?
