I love visiting this airport. I love how the entire airport does not have carpet! You can easily maneuver your luggage without feeling like you're pulling a ton of weight behind you.
There are very high ceilings and tons of escalators to get you to each terminal. You can gamble while waiting and eat at the many restaurants and food stops. They have smoking areas for those who smoke, you have to make sure you are inside the smoking box to actually smoke. They have gambling stations inside the boxes too for those who are smoking.
There's tons of places to shop if you wanted to shop while you are waiting.
Safe travels
