On the Dutch-side I would guess it is the same water in the resorts and we have never had a problem. Unless a place is buying bagged ice, the ice is made with the same water and any vegetables, salad (if not out of a bag) and dishes are washed with the same water. Not serving tap water would not stop me from going to a certain place but it is nothing but a money-maker.

Regarding pizza, I will take Orange Fever, Pizza Galley, Busby's was good the one time I had it and Driftwood. I will avoid BBB and Pizza Pasta.
