The pool water is nice and warm! We go every January, and my kids always swim at night!!! This past year it was 45 degrees and there they were in the pool. We were bundled up in coats and gloves, drinking our frosty drinks from the bar while we sat on the lounge chairs and watched them! The kids were fine until they got out!! haha.. then we had to run back to our rooms! lol I think you will be fine in November.
