Found this when I was booking hotel accommodation for xmas this year. It took $300 off the final tally for me. Exclusions seem to apply from Dec 22 -Jan 05.
T&Cs:
Book a qualifying hotel between October 13, 2014 12:01AM CST and October 15, 2014 9:59AM CST, for 1 or more nights for travel between October 13, 2014 and March 31, 2015, via CheapTickets and instantly receive 20% off through the use of the promotion code. Limit one discount per hotel room and one promotion code per booking. Discount may not be used toward the booking of a vacation package. Discounts are not redeemable for cash for any reason. Promotion codes are non-transferrable, not for resale, and cannot be combined with other offers. Any attempt at fraud will be prosecuted to the fullest extent of the law. Void where prohibited, taxed or restricted. CheapTickets reserves the right to change or limit the promotion in its sole discretion. Most major chains are excluded, to find participating hotels look for "PROMO CODE ELIGIBLE" message.

Hope it helps.
