Loooove the arena. 4.5 stars but bumped it up for the venues here.
As far as boxing goes, there's no blind spots... Things that make this place different are the high bar where you can watch and socialize, plus there are so many food options: hogies, personal pizzas, salad bar what?!! And a shake shack!!! Yummmm. Also there's a LOT of mini bars and drink carts for quick drinks. Cost wise, everything is what you'd expect (normal big arena pricing).
Only bad things are parking is hard to get to and lines to get into the arena itself are long. But once you're inside it's spacious and fun. Another bad thing is for concerts... I've been here for one of the opening concerts and wasn't a fan of the layout for the stage. Some seats were too far to the side/back of the stage to see well but there's not too many of those.
Good outweighs the bad and overall a great place for events. Glad we finally have an arena in Vegas!!! Next up a professional sports team?!! Hehe
