As a non-premium seat holder, I'm pretty unimpressed so far.
Disclaimers...I know the project isn't fully completed, and I'm still bitter about how misleading I feel the reseating process was.
Bathrooms on the upper concourse: I know there will be another set opening up next year, but did anyone else think that these were ridiculously small considering well over half of the assembly hall capacity will be using them? I figured the restrooms would be designed so that one end would be the entrance and the other would be the exit. Now you still have to walk through everyone waiting to get out of a single doorway.
Space on the upper concourse: I expect this will improve next year once construction is finished and you won't have so many people wandering around gawking like they were last night, but it was an extremely tight area in which to walk around.
Concessions: Minor issue, but don't try to sell me half the popcorn that I've been getting for the past 5+ years for the same price I was paying before.
opcorn:
I'm wondering what kind of donor interest there's going to be during the next reseating cycle in 3 years if the quality of the team doesn't improve. Right now there's nothing about the stadium that makes me want to maintain my level of giving.
