Nice and spacious events center with many food/drink windows open so there was never too long of a wait for anyone. Went for an Ariana Grande concert the other day and I was expecting it to be really crammed but the way they set up the seating was really good and you could tell everyone had a nice view.
As for parking, the best place to park is the self parking garage. I came in from Frank Sinatra after I got off the freeway and entered in the back. They opened up the rooftop floor, which is normally employee parking, so I went straight up there and found parking rather quickly and only came 30 minutes early. Took the employee elevator down to casino floor, made a right at Lupo, right and Fleur and in under a 5 minute walk, I was at the Events Center! I'm giving a detailed explanation of my walk for all the ladies wearing heels! lol and the way I went was rather quick so there you go! :)
As for leaving, of course some traffic but overall a pleasant experience! I would definitely see a concert here again.
