The best buys in Cozumel are Silver (make sure it is genuine .925%), marble/onyz chess sets, Tequila, and cotton rugs, hammocks and tops. Do be carefull if you buy the cotton articles when you wash them they could shrink a lot. Check out Poncho's Back Yard for a nice cool drink inside the gift store at the end of the main street. Anyone from the ship will be able to direct you. It is a lovely spot to relax after a great day in Cozumel.
