This is by far the best airport on the west coast. They have plenty of parking, very accessible, plenty of restaurants and shopping, easy to navigate and the addition of the C terminal was huge.
It's easy to get into and easy to leave in many different directions. Not to mention the view of the Las Vegas Strip as your coming and going. It's breathtaking.
Also if your a gambler you can always try and hit a jackpot at the airport as there are plenty of machine scattered around the Vegas airport.
