Last year a buddy had to dump playoff tickets a day or two before the game. By then everyone knew it was going to be 5-below so he only got $30 for them.
Seeing as how bad snow is a given, it might be rock bottom time for prices right now. Cheapest tickets at the moment of this posting are $99 not including fees.
As for getting home it's going to be really bad around the stadium but better as you get close to the city. I won't venture a guess on how long it will take to get back. But if I were you I'd park further from the stadium and on the side of the road exiting away. You don't want to have to cross lanes to get out.
That would be eastbound Southwestern, northbound Abbott or eastbound Big Tree, but this is important, well past the stadium lot exit become police shut Big Tree down for a long time to let people out of the stadium lots first.
