I guarantee you that your Disney vacation will have a day or two of rain. Disney World is in Florda afterall (that means "showers" from late April to early October)! However, this will most likely not ruin your whole day Ive got questions from family/friends & saw questions on here & wanted to help....If you are at Disney & it starts raining, find a place to hide for 30 min...more than likely that is the worst of it for at least 2 hours...enjoy yourself & plan for the next downpour!
