I order a gallon of distilled water from Garden Grocer as part of our order from them.
However, during our recent November trip I asked at the cashier at the Wilderness Lodge Merchantile store if they sold distilled water. I was told
they DO sell gallon jugs of it. They keep it in the back and you have to ask for it. The price was reasonable -- not as cheap as say
walmart or Target, but about the same as Garden Grocer (but no delivery fee or minimum order).
During the same trip we were in another resort's store and actually saw a couple gallon jugs of distilled water out on the shelf, but I don't remember which store it was.
My
GUESS is that many of the resort stores actually DO sell it -- probably your best bet is the stores that sell medical type things like tylenol and such, and at most you will probably have to ask the cashier because it will be kept in the back. However, not a guarantee so it may be worth contacting your resort ahead of time to confirm it is available and that they will have enough for you on hand.
But, there are delivery options, too.
