Great place, but had a problem this last time.

Great place, but had a problem this last time.
We were there for a concert. I need a wheelchair because I can't walk far without resting/sitting. My family and I waited FOREVER to get a chair, and the concert even started when we did get one. Missed the first act. :( The problem was there wasn't enough people to push them. Also, the building only has ONE ELEVATOR!?! Good grief!
