It depends on what time you want to get there. If you are going to be there when the stadium lots open then lot 7 parking as close to the exit as you can get is the way to go. If you're going later avoid the stadium lots because you're going to end up in the back & it will take what seems forever to get out. If you choose the stadium lot, get a parking pass in advance.
Great seats, but don't expect to ever be able to sit in them. Everyone stands the entire game in the lower bowl & don't forget Highmark is a cashless stadium.
Have a great time & don't get into any fights.
