When we went to WDW, we visited Fantasyland 5 times in a week. Never once was it "a mess" and nor did I once get the lasting(or unlasting for that matter) impression that I should ever feel that I should "avoid it". Each time we visited Fantasyland we enjoyed every single attraction, without a single wait and absolutely no crowds to contend with. And that's at various times.

No waits on Splash. No waits on Big Thunder. No waits on Space or Buzz. No waits at ToT or RnR, Safari, Dinosaur, Dumbo, Triceratops, Primeval, no crowds for Wishes, no waits for lunch or dinner. Ever. In 8 days.
Yup, the philosophy and tour plans are that good. And that relaxing. I enjoy having a listed order of rides, it means I don't have to think. And the orders are always very organic and intuitive. Also, I was able to make my own tour plans because I understood the mentally of the crowd pattersn, so in MK, I followed Mike's plans to the letter. In Epcot FW we made our own(now, with the additional attractions, I'd follow his), had an awesome time.
We did not go home tired. We did not go home jaded. We did not go home disappointed or underfulfilled.
