My mini me and I were there to see the Disney On Ice show.
Drive to the US Airways Center could take longer especially during rush hour. Parking is located to right next to the building on the third street side. I would recommend reserving space ahead of time by going to parkwhiz.com. If you park on the second floor, there is a walkway directly to the US Airways Center, east side entrance. If you have your tickets at Will Call, then walk to the first street side for the main entrance to pick up your tickets.
Plenty of friendly staff around to guide you to where you need to go, and lots of bathroom to accommodate so many people. Clean bathroom is always nice.
Food was on expensive side but expected for a place like this. Besides the standard food, the Disney On Ice set up booth to sell popcorn, ice cream, cotton candy with high price... When a little innocent face plead with cute eyes, why can we say no to that? I contributed fair amount to the Disney On Ice production company from my purchase for my princess.
US Airways Center is set up to accommodate large crowds, they sure know what they are doing. We really had a great time last night.
