I've sat in section 527 twice over the years if I am remembering correctly. I sat here two weeks ago for the first preseason game of this season vs. the Chicago Bears. It's a decent view, almost directly behind the uprights in the south end zone. Getting there is an absolute headache. After doing the 15 minute security/pat down process (no purses allowed), fans sitting on the upper deck are required to travel the ramps to reach their seats and it's a long trip. There are no escalators at this stadium which isn't all that surprising considering it was built in the mid 90's.
If you're a relatively tall person, you will hate these seats. My knees were touching the cup holder and unlike many NFL stadiums, Panthers fans stay seated for most of the game so you can't get away with standing the entire game.
There are plenty of restrooms and concessions available. You will have your share of BBQ items to choose from and the Carolina Ale stand has some great local beers to choose from. The concourses are easy to navigate but were plain and dull. The Panther statues out front and the Same Mills/Mike Mccormack statues are also a neat feature at this stadium.
You'll enjoy this stadium, it's much better than the Superdome and Ralph Wilson Stadium but make sure you spend some money on decent seats to ensure the best possible experience!
