As somebody who has done a considerable bit of flying and now lives here in Las Vegas, I like this airport a lot (enough to bother writing a review about an airport).
Free wifi (even before Google started sponsoring it), cheap passenger pickup meters (25 cents for 10 minutes), and relatively cheap short-term daily parking rates make things pretty comfortable. I can't comment on the slot machines, and the Mexican restaurant in the Southwest terminal is pretty awful, but I've never experienced a long wait in security lines. Making a short trip to California or picking up company coming in from out of town is pretty easy!
