With 34 rows in each section, the upper level sideline sections are the largest in the stadium. Fans in rows 25 and above will soon learn that it's definitely worth the money to be in one of the lower rows. In addition to a better view of the field, the lower rows have better access to the upper concourse. When you're holding four over-poured beers, the fewer the steps, the better.
The west side of the stadium is slightly more popular than the opposite sideline. First, the Panthers bench is on this side of the field. And second, this is the less sunny side where the sun sets behind you. Ticket prices generally don't reflect those differences, so you can find good value on that side of the field.
