Not going to lie to you. We often comment that the pool feels like bathwater. But it also will at the Contemporary, or the Polynesian, or All-Stars or Saratoga Springs. In the summer in Florida temperatures are normally in the mid to upper 90s. You have to expect that the pools will be quite warm. I sincerely doubt however, that they are heating the pool in addition To Mr. Sun doing his job.
That said, even bathwater feels refreshing when the temperature outside feels like it's over 100°. And we find the pool here at BC/YC along with the pool at BWI to be refreshing despite the fact that it is not icy cold. For comparison purposes, we live north of Boston, and are just emerging from a heatwave, and we're discussing the fact that our own pool at home feels like bathwater at this point. It's the curse of the summer. But hey, you're at Disney World, and it's better than no pool at all, right?
