This isn't a huge airport, but dodging slot machines and construction makes it seem that way. The baggage claim area is huge and seems disorganized but somehow works.
The taxi line is long but moves really fast. When you get in your cab, make sure they don't take you way around on the west side of the strip through the tunnel. That'll add an unnecessary $10 or so on the fare. If you're dying for an In-and-Out Burger (when there are so many great restaurants in this town!), that route is for you then.
