From right now until the around March 18th are the busiest times, and it's still quite busy until the end of March, first week in April.
cheers for that. it would have to be april cos of work, is it still bangin in the first week of april
that's when I went last year, and while it is not as crazy as the weeks prior, there are plenty of people in Cancun partying that week. the clubs were still packed all week, lines out the door. no worries sir. Check out the 'Breakers Forum' instead of the 'Cancun Info', you'll find more information than you can handle. good luck
As long as you don't go after the first week in April then you should be fine. Otherwise I have heard that the crowds really thin out quickly after that time. 212eric
