If you want roaches, laughes, chills and a few sleepless night on the cheap then go with the AAU & Motel 6 discount.
Motel 6 CP540332 <---- promo code
AAU is American Atheltic Union, open to anyone to join although the rate code usually never requires an official AAU form of id. If you wanted to play it safe, just go over to the AAU and register yourself with them, a years membership for most sporting catagories will set you back around $12. I've been forced to ditch the Marriott's for a M6 when with my team and I've used the above code to snag rooms at or under $35 a night... roaches and cold sweats were always complimentary^
