These are the best seats I've had at Metlife Stadium. I've never been able to afford tickets on the main level so I would be very happy here for mostly every game. Don't have any recollection of our exact row but it was kind of in the middle of the section, climbing the steps to our seats didn't require too much of us. The usher was more than happy to show us to our seats when we arrived. They DO check tickets on the upper level, that's not just a lower level thing.
Concourses on the upper level are smaller and a little tighter and are also very plain. There were plenty of tvs scattered around though, so I never felt uncomfortable about grabbing a beer while the game was going on. I do like the activities that the Giants offer fans before the game in the parking lots. A lot of the activities are announced on the team's website the week of the game, so check there. They reveal everything such as who is singing the national anthem, etc. Have fun at the game!
