walking too and from is nice, especially considering if you might be in an impaired position once the game is over LOL If I was going to games all the time, I wouldn't spend the 800 bucks extra. But if it's more of a once or twice every few years trip and i'm there for the entire experience? Take my money. Then you're not worried about anything. You walk out your door and you're at your destination practically, can take in as much as you'd like or go back and take a nap or whatever you want.
But i live near Appleton, I always leave a good 4 hours before the game, almost no traffic there, get to my tailgate spot and have almost 3.5 hours of grilling, eating and drinking before the game. The drive is pretty easy, once you get in that 2 hour before kick off area, it's a slower drive, but still not bad. I'd rather relax at my tailgate than in my car, but that's me so i leave early. If it's not snowy it can be about an hour and a half back to appleton after the game.
But it is not a difficult drive and there is a lot of parking within a few blocks of the stadium.
What game are you going to?
