I was thinking about refilling our water bottles for the park the night before to chill them. Do the fridges in the deluxe hotels have a freezer section on top? freezing would be even better.
I don't know about deluxe, but at Port Orleans, the freezer section was tiny. You might be able to fit one waterbottle in there, but that's it. You can refresh your waterbottles with cups of ice from most places that sell drinks in the parks.
