I attended Fleetwood Mac concert for the 1st time on December 10, 2014, where I was just behind the floor 'pit' on the incline front / center: Section 108, Row 6, Seat 4. US Airways Center did a professional job accompanying the event. Security and the ushers/usherettes were polite; just so you know to hide your water bottle ;) You have to walk through security (like the airport) with your arms up; just don't wear too many metals ;) Take the Metro Light Rail for free(!) up to a few hours before showtime- just show your event ticket when asked on the train (you'd be surprised to meet many people on it also going to the same event ). The venue was large & spacious enough to accompany an event of this 'magnitude' (i.e. veteran rock concerts); however, the seats were small and walking the aisles to get to your seats were very narrow that some had to get up and stand back with chairs folding back up for others to walk by to their seats. the inclines all around can feel a bit steep for those afraid of heights. The sound system was at a comfortable level that it didn't break your eardrums. The air conditioner was set on and the more people filled up, the more it did get a little warm. I did not eat or park there so I won't review them; I'm too cheap and wouldn't dare engage in Highway Robbery with them- just eat a big meal before the show at home or somewhere else cheaper ;) The Merchandise windows were big enough for me to view what souvenir to purchase. The restroom was clean.
All-in-all, I wouldn't mind attending future events there- as long it was something I'd want to see badly!
