Disney pools are heated, but…Pools at Walt Disney World are heated, but if you’re staying off property or in a vacation home that might not be the case. Some heat the water, but some don’t. Even if the weather is warm, the water in the pool will be cold if it isn’t heated. Water temperature does not rise to a comfortable temperature just because the air temperature is high. If you want to take a dip go ahead, but be ready for it!
