All these folks have such good memories, I bought a dozen bottles on my last RCI cruise for about $24, cut the cost down by a 1/3. When you get on the ship they will have a table set up in the Centrum, selling bottled water packages, you sign the ticket and they deliver it to your room. Not a per day charge, but a reduced price for a number of bottles, we shared it between 4 of us. Just clean out the fridge, put their stuff on the top shelf in plain view so you won't be charged, and fill the fridge with your water. There are times that tastes as good as my wine. Most times I just have both.
