I arrived at the Las Vegas Airport on a Saturday, and left on the following Saturday. There was a very small line to wait each way, and the people that work here actually want to help you!
What sets this Airport apart from others, is the ambiance it gives you. Right when you walk off your plane, there is an immediate immense line of slot machines all throughout the airport, which tells you right off the bat that you are now in Vegas!!!
There are a bunch of little restaurants with delicious smelling features fanning away as you walk by. I didn't get a chance to dine here, but I got to drink my favorite Jamba Juice, and eat Auntie Anne's Pretzels.
One thing I did not like was the women's' bathrooms, they were filthy and disgusting. Each stall had an odor of 800+ stinky blood clot vaginas' smeared across the wall. It felt as if the custodians weren't doing their job at all.
I would definitely come here, but try to use the restrooms in the restaurants - not the ones that are out to the public!
