Yes, the resort pool is heated year round. In Nov, I would definitely get pool heat if you're in a townhome or pool home. It can get cold at night and all the heat escapes from the pools, even if it's a warm day out the pool will still be cold if you don't have it. We've had enough people say they needed it in October actually.
But too cold? Nah....not if it's nice and warm! We sat in my pool in January watching the football playoffs in an 80 degree pool while we watched the Bears in the snow back home in Chicago! hehe
