Was just there about 10 days ago. The pool was warm, so it must be heated, but it was not super warm. The days I were there it was a bit cool (mid 60s during the day), so it was fine, but personally, I would have preferred it warmer. I spent my time in the hot tub.
In the summer time, with weather in the 80s and more plus humidity, I'm sure the poll will be plenty warm.
