Hi, MD - welcome to the Forum!
I wasn't in the Red Zone, but I was in GA, right across from it in Vancouver. It was set up on the outer rail (outside the B stage circling the main stage) on Adam's side of the stage. They had a souvenir booth set up at one end (until the break between BEP and U2).
If you don't want to stand in line for GA all day

and still be close to the stage, I think this is a great way to go. Plus, you're helping a great cause.
