I had come to the Thomas & Mack Center for several events ranging from basketball games (Woo - Go Rebels) to boxing matches. Ultimately, for a city like Las Vegas, there should and will be better arenas for high profile sporting events but the T&M Center just doesn't cut it for a good number of reasons.
Concession stands are overpriced and terrible. The seats are not comfortable (I've sat in the nosebleeds to close to the floor), ticket office customer service is whack, and the traffic is a mess when these events finish. Don't get me started on the bathrooms during any event, the attendant is too busy being lazy to clean any messes that occur.
Aside from UNLV students and diehard sports fans, I don't know too many LV locals who really enjoy coming out here. Often times this means there are always seats available for even some of the most popular events, but like most folks I'd rather catch it on TV. I was shocked they were able to host the NBA All Star game here last year with very little problems. I anticipate that Las Vegas will rebuild this joint in the next decade or come up with something better altogether.
