3. Cozumel, Mexico
Start the day off with a tender ride from ship to shore, then head to Tulum for a historic walk among more than 60 temples in this ancient Mayan city perched on a cliff rising high above the turquoise Caribbean Sea. Make the extra effort to climb down the winding wooden staircase to the beach for at least a few minutes of splash time in the shadow of the majestic ruins above.
Shore excursion $99.
