The Hilton in Downtown Atlanta is running special rates for stays in November and December, as low as $50 per night. The rooms can be booked directly at http://www.hilton.com and you can use the Promo Code 0002635191 in honor of Team USA for the upcoming Olympics.
There are even flexible/cancellable rates, so even if your plans are tentative, grab a room tentatively (make sure it’s a refundable room for your particular dates) to lock in this rate!
