Had to wait outside in the cold for almost 2 hours outside when the concert was supposed to start at 8. Some of the entrances were not open since the security system did not work. Even inside, we waited for an extra hour for the artist to perform. The sound system was bad at the beginning too, they made the artist go off sync with the music. The chairs are made of plastic and are uncomfortable. A$AP Rocky did a wonderful performance but due to the concert starting so late, he performed for less than two hours. Overall a horribly organized concert and arena.
