I went to the iheartfestival at the T-Mobile Arena and it was amazing. The stadium itself is so large and spacious with the park outside. There's an outdoor patio lounge for smokers but good views as well. You can see the entire arena before a show starts and everything looks new and clean and of course charging stations and many bathrooms. Seats are comfortable but did not notice cup holders. Lights are awesome and the speakers are effective.
