The pool temp should be about 80 degrees. Warm enough for us "northerners" to swim anytime of the year. I've swum in October, November, December and February as I never go to WDW without getting in the pools! The air might be cool once you're wet, but it's just a short trip to grab a towel. At the All-Stars you will have to bring towels from your rooms, but you can request housekeeping to bring you more. These are not huge, fluffy towels, but work well enough!
