I think it has had the effect of lower standards, but not from a guest point of view. I feel like WDW doesn't offer the greatest quality of food, especially quick service because of the free dining. They realize that half of the people are getting it "free" so why offer a better quality product, when they can still get the other half to pay for it as well. I remember Pecos Bills being one of my favorite places to go, and loving the burger there, but over the years, the quality has gone down drastically and I can't help but feel that it is because of the free dining. We don't do any of the QS anymore with the exception of the food court in the land pavilion. Don't get me wrong, there TS places that have poor quality as well, Tony's is a perfect example but I don't feel like people lower there standards of what they expect, I feel like WDW has.
