Mccarran can be an animal if there is a ton of tourists coming into town (which is to be expected), but I have had an overall very good experience with this place. I am new-ish to Vegas, so this is my new hometown airport. Because of this, I have a different point of view than most people that fly in and out. For my personal and business use, I have always had an enjoyable experience. The airport is sprawling, but easy to navigate, and plenty of food/shopping options. Also, since it's Vegas, I have access to destinations the world over.
