Disgusting.  Going to this airport is like going to the shittiest casino ever.  It smells, looks and acts like a shitty casino.  The good news is that if you're in Vegas for the first time the airport gets you ready for what you're in for.  Lots of smoke, lots of slot machines, lots of badly dressed people and lots of bad tattoo choices.  If I could upgrade this review by a half star for the awesome people watching, I would.
