Going to the airport is never any fun anywhere, and maybe its because this is the Las Vegas airport, but its my favorite in the US. The happy slot machine sound, and the fact that it has (at least the time of my last visit) free Wi-Fi in the airport. Sitting in the airport is boring, so sitting in the airport on a laptop browsing the web is less so. It also has a good selection of places to eat. Granted, they are expensive, but I can't think of any airport where this isn't the case.
If I have to fly anywhere, I always feel a little better if its to here.
