Heated Pools in the Winter?

We’re going to be staying at Portofino, I think, in January. Do they keep the pools heated during the winter months at Universal like they do at Disney, and do people actually swim? I personally don’t see myself eager to jump in a pool, but I’m pretty sure my daughter is going to want to go swimming, regardless of the temp…

Beach, Villa and Hillside Pools are all heated as far as I know
