When is the best time to go to Cancun. Which month?

The best time to go is in Spring Break, between March 15 - April 15... It's a non-stop party.. I reccomend you to get a All-Inclusive Resort where you can drink and eat all you want.. They don't have this in Brazil.. Anyways, ty to stay on the North area of Hotel Zone.. Go to Hotwire.com you will get the best deals..
