When you’re not diving into the crystalline waters of Cozumel, drop into a cozy hammock made for two and snooze. Rest up to explore the Mayan archaeological sites at San Gervasio, home of the Mayan goddess of the moon, Ix Chel. Plan your trip to Passion Island or tour of the Punta Sur lighthouse. Think about which beach club you’ll visit tomorrow and what time you should book your couples massage. Most important, plan a date to return to Cozumel.
