I haven't heard anything about the waterparks being heated or even the pools for that matter. With the amount of water that Disney uses can you imagine what it would cost to artificially heat that much water. The Florida sun does that nicely. If they only have a couple of cooler days the water would likely hold a lot of the heat anyway.
Yup, by the sun.
It’s very well known the pools and water park waters are heated by actual systems to around 80 degrees. Take like 10 seconds and google it for yourself since you don’t believe us.
OK, I'll take your word for it, but if Disney artificially heats the water in what is a 90% tropical climate they are dumber than everybody gives them credit. The days that are so cold that it would cool the water are days that would require staying in the water to avoid hypothermia. When it is that cold there won't be many people in the pools or the water parks anyway. That is why they shut one down for maintenance during the winter months. I went there in February for many years from Vermont and even with my high tolerance for cold, I know I wasn't going to swim or expose myself to the cold air/wet body situation. I might go to an indoor hot tub which I'm sure Disney would heat.
