Purchase a ticket and join the fans at a game at Andres Quintana Roo Stadium. If there's nothing scheduled while you're there, you might like to check if they give a tour of the grounds.
Andres Quintana Roo Stadium is a great place to begin exploring Downtown Cancun. This sporting facility comes recommended by fellow travelers, but it's not the only spot to see here. Allow time for other sights like La Isla Shopping Mall, Tortuga Beach, and Plaza Las Americas to fully appreciate what the area has to offer.
