This is probably the best airport for people watching. Where else do you have both slot machines, indoor smoking rooms and liquor stores?! The people headed to Vegas are all bright eyed and excited, while those leaving Vegas are seemingly always on the opposite side of the spectrum. Never will you see such a contrast in faces and attitudes than you will here.
As for the actual airport, I find it in need of a few upgrades. It always smells of old cigarettes and tragedy. The look and feel is very dated. Seems to always be some type of renovation happening but not much seems to get done. In the old part of the airport the bathrooms seem to always have the porta-potty smell. If it wasn't for the amazing people watching, I'm sure my review would be worse...
