I don't know if it was mentioned (I didn't read through all the posts), but I don't send water to our resort. Instead, I pack a Britta water pitcher. I usally stuff it with a t shirt or 2 to make sure it doesn't crack in my luggage.
Then every night, we filter a pitcher of water and it gets rid of the yucky smell/taste. Then we fill a few water bottles half way and stick them in the freezer. The next morning we fill the bottle the rest of the way with more filtered water.
The water bottles keep cold for a long time this way, it's much cheaper than sending down water, and we are keeping plastic out of landfills.
This year, we will be using our Disney Britta pitcher for the 5th time!!! The same pitcher!!!
