Oh, I dont know - any night is busy depending on season you should expect from 50 to 400 people on any one night. Especially now as others mentioned there is only one option for the bar tour. As far as I know the only night of the week they dont go is Sundays. Also there's my other site at Party Hopper Cancun - Cancun Bar Crawls
I agree with Steve. Now that's there only bar leaping tour going it's going to be popular every night. So just pick the night that best fits into your plans. Youcertainly won'tbe alone on the tour...or in the clubs. :lol:
