9. Visit in the Cooler Months
Contrary to what you may believe, you don't haveto visit Disney World during summer vacation. In fact, the cooler months of the year are the far better times to go. Try visiting in October or November, or even early December (do NOT go during the week of Christmas or even the one before it, trust us). You can also try January or February.
Whichever of those you choose, you'll still have warm middays but pleasantly cool mornings and nights. There's nothing better.
