Leaving on Celebration June 2nd for Calica and Cozumel. Myself(39), Husband(39) and son (19). Looking at different trips to take. This will be our first cruise. In Calica we are looking at taking the bus excursion to Cancun. In Cozumel either the Fiesta Party Boat or the Catamaran Snorkling and Sail to Beach. My son wants to Snorkel and we want to go to the beach. Any suggestions on the best excursions?
