I don't like this airport. Straight up. I mean the only thing I DO like about it is that "you're in Vegas!" or "ok, it's been a blast, time to go home" other then that, nothing special about this airport. I don't like taking trams or to get within the same airport and McCarran has it.
I come here from southern California and when I land, I usually want to get the heck out of here! Part of it is because I don't like the airport, and the other part is I wanna get on the strip... it's 50/50.
A big plus for this airport is FREE WI-FI! It was a 2 star, but I'm a sucker for free wi-fi, I think it helps in so many ways and cuts your wait time down significantly (if you're bored of course)
