Quality Inn, $61/night (incl tax) with Choice Privileges membership. Room is booked.There are several national chain hotels in Auburn. All are right off of I-69. My recommendation would be the Hampton Inn, it's the newest Hotel, only been open a couple of years. All are very close together, and near several restaurants.
Checking Hotels.com, it's only $79 a night at that time. Don't try and book during the ACD festival, it's probably triple that!!!
