We attended the Trans-Siberian Orchestra show over the past weekend and it was definitely a well suited arena for this type of event. The arena was a little more than half full and it was easy to find our seats with the helpful event staff. I had a hot chocolate since it was a tad cold in the arena, but it wasn't very good, so I probably wouldn't order that again.
The fountain outside of the arena was very nice and there were plenty of places on site to eat if you wanted to stay close to your event / show. The parking wasn't terrible, even when leaving, it seems that there were an adequate number of parking staff persons and exits to ensure that everything cleared out in an organized and easy manner.
Overall: B+
As with all arenas, the food / drinks / parking is pricey, but the overall ambiance and ease of everything make this a go back venue.
