When we were on the Victory we were given a galley tour and the one of the crew told us that the water that is offered on the Lido Deck is good for drinking but the water that comes out of the taps in the bathroom is questionable and should be avoided for drinking. I of course drank the water and had no ill effects (maybe a ploy to sell more of the evian water provided in the cabin?)
We were told the water that comes from the taps in our bathrooms is good water. So we took water bottles along to do that same thing. Thought we would save some money. Well the water at dinner was great. But sometimes the water coming from the taps in bathroom were brown. No way were we drinking that water. Maybe just a fluke but we stayed away from the taps. We bought our bottled water on the ship and when we went ashore too.
