I don’t think you actually are. Because Anaheim wants Disney to stop using overflow lots. Darkbeer provided a good summary of where things are and why certain things are happening.Oh, I'm taking into account the entire picture. On site parking is a luxury that isn't going to be returning to cast members ever again. There is no on-site parking even for park guests. Disney has overflow options like Anaheim Stadium and Gardenwalk.
On most operating days (let me clarify- not all) cast member parking is a non-issue.
