The airport itself is alright, with slot machines greeting you to let you know you've arrived in Vegas.
The major downfall of this airport is the ridiculous taxi lines! At times they move fast, but when I was here mid August- Thurs night @ 11pm, I walked a whole maze and back waiting in the taxi line. Usually the taxi line weaves back and forth right outside the doors, but this time not only did we have to weave thru back and forth in this area, the workers also made us turn the corner of the building and weave back and forth.. even though there was no line there!!! They were just too lazy to unhook the ropes so that people didn't have to walk back and forth multiple times to get back to the original part of the taxi line... totally ridiculous when its 90 degrees outside and everyone has luggage. One guy even asked for a limo in the middle of walking through this craziness.
If you have a big group with you- get a limo instead... skip the lines and the treadmill workout of getting a taxi.
