I have never five starred an airport only because airports really are not my favorite places although I do need them. Now, I do like airport lounges but airports in general really suck. The day that I could be magically transported into my seat inside the plane and avoid check in, luggage handling and security in any airport or the "Hey, haha look slot machines" from tourists at the Vegas airport, I may five star an airport.
There are two terminals you can fly out of T1 and T3. T2 I am not sure if it even exists because I have never seen signs for it. I am almost positive it hides in another dimension. T1 is the older terminal and just driving through drop off can cause temporary Tourette's even with the sweetest of people. T3 is the newer terminal and drop off is like a pleasant Sunday drive in comparison with T1.
Depending on your airline, you may have to take an air tram to your gates so give yourself enough time. Other than that, this airport is pretty simple to navigate and has the typical restaurants, last minute shops and slot machines for those who just could not get enough Vegas.
The people who work here really are a hit or miss. Not unless someone is very rude to me in an airport or pulls me over for the so called "VIP" treatment, then I generally keep my head down and go through machine like motions to get myself to an airport lounge or a sit down restaurant. I do not recall anyone being very rude in the eight years that I have come through here. I have been treated to the VIP process of "Pull that lady over, search every part of her and everything she owns. She looks suspicious" random screenings. It just seems that everyone is doing their job and no hassles.
It is what it is people, an airport with the addition of "Hey haha look slot machines!"
