A huge airport!!! Give yourself plenty of time to pick up a rental car if you plan to get one. It is fairly easy to get to it though, just hop on a shuttle bus and it will take you to the rental car place!
And if you didn't have enough slot machine experience in Las Vegas, don't worry! there are plenty of these machines at this airport!
Also give yourself extra time to get to the gate on the return flight!!! again, it is a huge airport!!!
