My wife and I recently went to Las Vegas, Nevada primarily for a reunion with a brother and an old friend. But of course, we went to the casinos. My wife loves the slots!
What we found was that all the casinos on the strip that we visited were not paying! And, all the people we talked to were very frustrated.
It is our belief that if you want some waging satisfaction, go to Arizona. The tribes are paying out according to Arizona state law. There is no doubt, in my opinion,  that you will make more than if you stay in Nevada. Hotel rooms in Nevada have been discounted (for the summer 2012),  but when you get there you will pay highly for food, taxis, gas, clothes, and much more. If you would like a vacation with desert, mountains, friendly people, and sun, go to Arizona!! For goodness sake, give it a try! What do you have to lose?
