This review is for the Coliseum and not the Expo Center. With that said, this was the first time I've been inside the Coliseum. Parking is $7.
The attendant said, "Go to the right, to the West Lobby" when we asked where to redeem my Groupon voucher. Follow the signs to "Advanced Tickets." there are plenty of parking on the west parking lot and will call is through the doors. There will be plenty of signs and easy to follow.
In addition, the Coliseum is very easy to navigate. There are only 3 stories. There were no long stairs, thank goodness. While inside, it seemed a tad dated but clean. There are plenty of men's and women's restrooms on each floor.
I just wished there were hand rails when going up to the nose bleeds section. I felt bad for the older women that took almost 10 minutes to walk down or the guys that tripped walking up and almost fell backwards.
All in all, the sound quality at the event was crystal clear. The seating was comfortable for me; no cup holders. I can't imagine how it would be like for someone with long legs though. I'm looking forward to more events at the Coliseum.
