Thanks for that pic - that's really helpful! We've always held our kids, too, (on our hips or backs) but with my youngest being almost 8, that is becoming impractical (for me at least... DH can still handle it). I like the idea of at least having a railing we can stand behind so there won't be anyone IMMEDIATELY in front of them. It always seems like no matter where we go to watch, someone steps in front of us at the last minute... and I don't blame them really. They have to squeeze in just like everyone else. But it's still annoying.
Also, even if this area does get crowded, at least it's a bit separated from the insanity. And if I have to camp out an hour before the show, I would rather do it here where no one is going to step on me or run over me with their stroller. I have a super thin picnic blanket we can spread on the ground and relax before the show starts. I really hope this plays out as well as it seems in my mind.
