Our Carnival Cruises Celebration sails year-round to offer you a choice of three less than a week vacations every week of the year. The 4 day cruises to Cozumel sail on Thursdays to give you a long weekend away from the cares of the world. The 5 day cruises to Cozumel and Calica/Playa del Carmen sail on Mondays and Saturdays. Whichever cruise you select, you'll experience the best of the Western Caribbean. Shopping for silver and native handicrafts, exploring ancient Mayan ruins, windsurfing, diving, snorkeling -- the choices are endless!
