We had GA for both shows, and agree that it seemed more crowded than three years ago. We didn't camp out or line up at all, arriving on the floor around 7:30pm, still easily getting pretty much the spots we wanted. Night 1 we were two rows back from the middle of the ramp on Edge's side. Had Bono and Larry directly in front of us during their features, but of course, couldn't see the screen very well from so close up. Didn't seem overcrowded where we were, but the areas toward either stage were jammed, and this was exacerbated near the e stage by the VIP platform on that side taking up more space.
Night 2 we wanted a broader view of the production (especially the fantastic intermission video), so stood right by the RZ entrance on Adam's side. The Celtics mascot walked right by us there before the show - oops, it was really Joe O'Herlihy. Garden security was clearly frustrated with having to keep the EdgeLane clear throughout most of the show. That area was VERY crowded at first, then eased up as the action moved to the main and e stages - but got packed again during SATS, as everyone knew Edge would be coming. After COBL, the floor seamed to "relax" a bit, and we wormed our way up toward the main stage, settling on the RZ rail, about halfway between the RZ entrance and the stage. Not "close", but still a great view.
Nice moment was when one of the two big guys next to us let a 5' girl move to their position on the RZ entrance rail, as she was having hard time seeing anything. Well done, gents.
