Park downtown at the intermodal. The bus is free to carry to and from the stadium and the parking is free there. Get there fairly early if you want a place to park though. There are plenty of good restaurants downtown as well. I am surprised you can find a vacancy for the Auburn game. You can also park at Central High school which is pretty close. 20 to park there I think. Do not park on the east side of campus as they will funnel you toward McFarland Blvd and you want to stay away from there at all cost. Take the 359 Bypass if at all possible.
