2. Lack of Needed Items
Lack of planning means inadequate packing, which in turn means a few things are sure to be forgotten. While this isn't the end of the world, it sure can be a pricey problem to have when visiting Disney World. This is because most things found in Disney shops are quite overpriced, meaning that a forgotten swimsuit could be a $50 mistake. Forget three or four things, and you’re looking at spending hundreds of dollars, something that could’ve been avoided with a little forethought.
