5. September and October – Kids are still in school and some parents aren’t willing to pull them out mid-year for vacation. This can be one of the best times to visit. It is still quite hot in Florida, but if you time your trip right, you can experience Mickey’s Not So Scary Halloween Party and see the parks with more fall-like decorations. You get a little different experience that you can’t get other times of the year, plus without the crowds.
