We're not here to judge: we know that most people come to Cancún to party. If you want fine dining and dancing under the stars, you'll definitely find it here. But if your tastes run more toward bikini contests, all-night chug-a-thons, or cross-dressing Cher impersonators, rest assured: Cancún has plenty of those, too.
If you want to avoid rowdy spring breakers, stay clear of "open-bar" establishments and chain restaurants like Margaritaville, Señor Frogs, and Planet Hollywood. You're likely to find them packed with party animals on the loose.
