re: Attending the game Saturday, driving from Bham to ATL day of, two questions:

I usually park at the Hamilton Holmes station. Easy to get back on the interstate when you leave.

Parking might fill up, so go kind of early. Train ride in to the stadium is always easy, but sometimes you have to wait in line for the train after the game.

ETA - there are huge lots on both sides of the station, so if the one next to the interstate is full, just go around the corner to the other side.
