I'm sure this has been asked before and so I'm asking it for probably the 100th time. Since we had to cut our trip to Disney short last week we plan on returning the first week of December during value season. We are going to be staying at the Poly. Here are my questions: 1. I know they keep the pools heated at the deluxes but do they really stay warm enough to swim in? 2. If the water is warm enough to swim in what's the outside temp like normally the 1st week of Dec??? Thanks!!!!
