So now, I've been to T-Mobile Arena for the Golden Knights hockey event, a UFC PPV fight, and a NBA game. I'm just missing a major pop concert - someone message me when T Swift is in town.
The place is great with not a single bad seat in the house. The jumbotron is indeed jumbo and probably with a 1,080,000p and 4 thousand-K resolution so everything is crystal clear. I dig the hanging concert-style speakers; you feel all the weight of the beats when they're playing music and there's plenty of reverb so you hear every word the announcers are speaking in every corner of the house. The walkways and seating are not cramped at all and there are a few charging stations for your phone (non-T-Mobile phones applicable).
The parts I especially dig are the Bud Light, Jack Daniels, and Hyde lounges. Especially the latter, it turns into a classy nightclub during special events.
Tip: if you're driving you'll probably need to park there too. Go to the T-Mobile Arena website and look up parking. The parking attendant told me locals get a discount if you prepay your parking.
Super great experience at TMA. I look forward to coming back time and the again.
