we were at the Polynesian last year at Thanksgiving. People were swimming, as were the ducks...the pools are heated, you could see the steam coming off of them at night. For the most part, the temps were in the 70's during the day, nice at night, but then again we're from Massachusetts, and we left in the middle of a snowstorm, so we wore shorts the whole time we were down there. I bought a sweatshirt for night time (I purposely left my winter coat in the car at the airport). There was really only one night that I should have worn long pants, but I wasn't giving in!!
