The coffee at DW has long been a sore spot among many guests. To put it simply: most of the coffee served in the parks and resorts is AWFUL. It is some type of Nescafe stuff.
(Understand, while I lovea good cup of coffee, I am not a coffee snob. I like anything that's decent: from Starbucks (very strong and somewhat burnt tasting) to Dunkin' Donuts (sometimes a little watery). My wife makes fun of me because I can often drink a cup of coffee that she feels is bad. With that in mind, I could NOT drink the Nescafe stuff at Disney. Itried on more than one occaission and never could tak more than a few sips.)
The Kona Cafe at the Poly had excellent coffee and has a stand in front. But the other restaurants/food courts there had the awful Nescafe.
In the parks, look for the coffee stands if you want a good cup. There are only a few, but they are usually pretty good. The restaurants in the parks did not have good coffee.
