My friends and I purchased EXPENSIVE tickets for a music concert to be next to the walkway stage that extended into the audience so we could see both the stage and the artists perfroming down the walkway. However, when we got there, the venue moved all the chairs back so that we were about 15 rows further back and we ended up BEHIND the sound board!! We couldn't even see the artists--then they had technical problems with the screens, so we couldn't even see those. Do NOT trust the Gila River Arena seating chart on the ground floor!!
