For employment with Disney, CP experience doesn't really help you stand out much, since there's a lot of CPs that are trying to use it as a stepping stone. For jobs elsewhere in Central Florida, they tend to have the "why doesn't this person work for Disney anymore?" mentality, and although it may not hurt you, it probably won't help much either. Outside of the Central Florida area, people who know about Disney's training and reputation for guest service will probably give it a little more weight, but others may not.
In the end, it's never a bad thing to have a Fortune 100 company on your resume, it just may not help you out as much as you thought it might.
