I love all the advertisement pertaining to the "Fabulous Las Vegas" especially the ones of all the cool new shows they had! I also enjoyed the slot machines they had in every room, but when I say enjoyed I mean from afar because I lost enough money ha ha.
The airport was relatively clean, but for it's size I can forgive some minor corners which weren't perfect. I'm a little spoiled since I'm used to the O'Hare airport, being one of the grandest in the country, so don't set your standards too high, its an average airport with relatively friendly staff [for an airport].
I like that they had many little shops of relatively diverse food since I don't necessarily like airplane food. I did not indulge on this visit because I was being cheap but maybe next time, I would recommend being patient with your hunger though because the food on the Strip is a lot better.
The only reason I actually deducted a star though was because the organizational methods weren't very great unfortunately. It took me and my best friend for ever to find our luggage... Google maps DOES however offer maps of the insides of airports... didn't think of that at the time though, haha..
