Seats do matter. Als sometimes hold a group of endzone seats for visiting fans. That's my bet as to where you are. They are low and close to the field, which is cool but the view is so awefull you can't tell if they ran for 20 yards or five. To make matters worse, the screen is behind you so you can't watch the replay of the play that you couldn't understand. All other seats are suitable except the first few rows on the North side which are too low to see over some of the sideline action.
You can get a decent pair of tix for about $100 on kijiji/montreal, a good hotel (which is important) in Laval for $100 night which makes for a decent weekend in Montreal, plus you sleep with your wife alone
Montreal is a great place to go, Via is offering 60% percent off now. The subway brings you close to the stadium from almost anywhere. It's only a 6 hours if you want to drive too. The only problem is when you go, you don't want your team losing 25-0.
