Still surprised at myself that I went to Vegas at all (granted it was for a girlfriend's bachelorette party), I was bombarded from the moment I stepped off the plane with slot machines EVERYWHERE with associated "casino noise". That alone pretty much summed up my trip - loud and crazy, with people and machines from every which-way trying to take money directly from your pockets!
The airport had a train you had to take to get to the gates and/or baggage claim, similar to the Denver Airport, which is far nicer. The layout of the airport definitely had ADD, with so many shops and restaurants in no apparent order. I think I found three Bijoux Terrier shops wandering around with too much time to kill before my flight. Thankfully, I was able to resist the urge to spend MORE money.
