With the Better Tomorrows promotion, now through December 31, 2010, for every night you pay the regular rate, you'll receive the next night at a 50% discount. That's half off every second night! 50% discount is applied to every second night and is based on the best available non-restricted rate. Better Tomorrows rates are prepaid and non-refundable. All hotel deals and offers are subject to availability. 6 night minimum length of stay required. (That would mean you would pay for 3 nights at 50% off and 3 nights at the regular rate).
