Clearly, I'm the crazy one, but, for the most part, I don't mind WDW water that much. And I live in the region of the country with the top rated drinking water in the country for several of the past ten years!
I will say, though, the water fountains over by Peter Pan and it's a small world are THE worst fountains at WDW. I think those pipes must be so old that you get a strong metallic taste on top of Florida water taste!
