Gammage is a wonderful venue for huge musicals!
Last week, I got to see Mama Mia, thank you Yelp for the complimentary tickets. We sat in Row 24 , Seats 46/48 and we had a great view of the stage. The people next to us left before the 2nd half, what the french toast! It's Mama Mia!
I've gone to Lion King, by myself and sat in row 13 in the middle and it's just as good, if not better.
I actually went to ASU, and performed on that very stage and love the fact that not only do big names perform there but also local performers and ASU students etc.
Yes, parking is not great, but really is it anywhere? I usually go early enough to find parking, around 6 or 6:30ish and hang out, have a drink and just chill. Even after the show, just wait about 20 to 30 minutes and you avoid a lot of the traffic.
Gammage is an unique building designed by Frank Lloyd Wright and if you are visiting the Phoenix area, it is a place to consider checking it out.
