The guys with the standing room thoughts are right. Depending on your agenda, most people like to be out and about, visiting all the areas of the park anyway. Plus, like stated, its really easy to move down seats.
If you want to lock in good seats, then i would just grab em from a scalper. I have probably done it 40 times for Phillies games and never got bad tickets. About 5 years ago i sold Flyers tix and got counterfit back from a scalper, that was the extent of any bad beats from tickets for me. If it was an Eagles game i wouldnt tell you to grab for a scalper.
I didnt realize the cash was counterfit, we were moving a ton of tickets that night. Ended up realizing it when i stopped at the OTB by the stadium and put it in a machine. When it wouldnt take it, i looked and didnt see the stripe. I think i sent about 10 diffferent people to Wawa to buy packs of gum, lol.
Enjoy the park, its awesome. You will love McFaddens,,, Its a good look
