Visited this arena for the first time because an actual, real NHL team was in town to face the lowly Coyotes, and we were very pleased with every facet of the facility.
First off, free parking is always great. Next, stuff to do before the game, like dining and shopping is always good. The in-game entertainment was on par with other NHL arenas, although the mixing was very strange. I'm pretty sure you can hear the bass from this arena in the international space station.
Also comfortable seats, friendly ushers, and a good variety of vendors. I also enjoy getting emails from this arena whenever discounted tickets are available when the Coyotes play actual competitive hockey teams. Hockey fans go to see and appreciate other teams than just their own.
