There is plenty of parking everywhere and a lot of people illegally park at hotels but no one ever enforces it and you can usually find street parking if you get there early enough. If you must pay for parking you can park for $10-$15 a mile or so away and then $30 right next to the stadium.

There is plenty of parking for the games. They tend to jack up parking for NFL games compared to other events but you can pay a lot for parking close by or get some exercise and walk a little and pay only $10.

Parking when you're there to see a NFL games gets real expensive due to it being so packed. You can end up paying anywhere up to $20. Parking and being able to walk to the stadium is cheaper and more convenient if it gets to hectic.
