If you are an AP holder.. and then get a job at Disney.. I **think** they can "freeze" your AP. So if you have 8 months left on your AP, they can hold those 8 months for when you are no longer a cm. I have a friend who did this because he started as part time as a second job and wasn't sure how long he could manage 2 jobs.. he jumped through some hoops to get it done, he's now been a cm for 2+ years and converted to full time, so I don't know how long they actually hold it for.
Also, if you are on property, you can try going over the casting building. It's across from Downtown Disney. You can ask them about what regular in park positions are open and schedule interviews.
