If you're planning on a hotel stay before March, 2013 you might want to book it through Hotels.com now -- they're offering a 10% discount to the first 15,000 people that book with the coupon code AUGUSTCA10.
This coupon code can be applied to hotel stays up until March 31, 2013 when you book by September 14 (while quantities last). There is a limit of one coupon redemption per person, so even if you cancel your first reservation you will not be able to redeem the 10% on another reservation.
Note: Most major chains are excluded from this promotion. For a complete list of excluded properties and coupon terms and conditions, visit this page.
