As an Oregonian, I'm a HUGE fan of our Portland International Airport. However, I can say that Vegas' peeps have a pretty nice airport.
What I like about McCarran:
* It's a huge airport
* Slot machines!
* Cute shops.
* Coffee Bean & Tea Leaf!
What I don't like about McCarran:
The garbage claim..I meant the baggage claim area is a bit depressing. I think either is the lighting or just the atmosphere made it look like an interrogation room area.
