My wife and I are going on a 7 day cruise in October with Royal Carribbean out of New Orleans. We are going to dock in Cozumel, George Town Grand Cayman and Progresso. This will be our first cruise, so any tips would be appreciated. We have swam with dolphins, seen the Mayan ruins, and snorkeled on previous trips to the Carribbean. Any excursions that'll you recommend that don't involve the ones I listed?
