In a lot of ways an airport is an airport. Is anyone reading a ton of review about airports? You don't have too much freedom to choose even if you read bad things. I live in Las Vegas so I fly in and out of McCarran often. Here's some worthwhile points:

-Yes, there are slot machines at the terminals
-If you go through a tunnel in a cab on your trip to the strip, you just got ripped off.
