I know how it happens, you walk into WDW expecting a relaxing calm day and before you know it, you've spent your life savings on egg rolls, Pal Mickey, and other items. (Let me just clear up that I have never purchased a Pal Mickey. K?)
Whether you're a local or visiting the park, the Magic Kingdom has a way of Magically cleaning your wallet. The most I've spent in the park was $3200, but that was because I took all of my employees for a treat in the park... long story. Realistically I usually spend about $100.
What about you? Has anyone ever unknowingly spent an ungodly amount?
