My personal opinion is that the water from the fountains isn't very tasty, but it is drinkable. I usually buy a bottle and refill from the fountains, though. when they sold Arrowhead water in the parks, the difference in taste between that and what comes out of the fountains was more noticible than now that they're selling Dasani. With the Dasani, I don't notice such a difference in the taste. You might want to try to find one of those Brita bottles. I am for my WDW trip.
