By far I must say one of the best airports in the country!
I love how when you walk off your plan you hear the instant chimes of slot machines...I don't gamble much, but that sound does make me smile.
The luggage pick up is quite easy and its not confusing nor is it in a cramped space like other airports. Its also not difficult to get a cab once you're ready to head onto the strip.
I also have to admit I do enjoy their security check point video that plays on the screens before going through to the gates. When you see Chubacka on those screens you know you're in a good place.
The one thing that sucks is that since there are millions of people who come to Vegas each year this airport can get packed, so you are better off coming early to check in for your departure flight.
P.S. If you're coming off the strip on a cab tell them to take Tropicana to the airport...This way you're fare isn't $25-$30. It's only like $13 if you're by the Wynn which is on the other end....
