Try to find shade. That Charlotte sun is BEAMING! Sat in the non-shaded side of the 100s against the Bengals one year. My son was shirtless before the end of the 1st quarter. I typically sit near the back of 231 in the shade, but I'd much rather be midfield somewhere.
Also, maybe not be a risk you want to take.. but I've had pretty good luck buying tix right before walking it. Sat in club level pretty affordably in Luke's last game.
