This is one of my favorite airports in the world. The shopping is fabulous, there are tons of restaurants and snack shops and you can play slot machines while waiting for your flight!
The airport is clean and well laid out for such a large airport. They have quick busses to the rental car center and taxis organized just outside of the baggage claim.
If you have never been to Vegas you need to visit before you die as their isn't any place in the world like it.
Enjoy!
