Not the best airport I have been to, but its okay! When you first come into the airport from your flight, you walk right into a big slot machine area that makes sure you know exactly where you just landed.
The airport is pretty clean and big. They have shuttles to take you to different sections of the airport. The lines are pretty long, but they move quickly. Everything in the airport is pretty expensive, but that's common in all airports. The signs are pretty clear for directions.
The airport is not anything awe-inspiring, but come on... you are in Vegas!
