For being an international airport, McCarran is virtually hassle free, which is great for locals (that's me!). The location is wonderful - very easy to reach from most parts of Vegas and Henderson. I don't miss driving an hour-plus each way to travel anywhere like I did in Colorado.
Parking is usually pretty cake. Security is typically a breeze. I have only been delayed on a flight once - which is pretty good considering the amount of traffic going in and out of that place.
Careful when you're getting on/off the tram to the C Gates...I broke my toe when my flip flop got caught on the edge! Big tree fall hard...
