Well, three years ago last week I started on the the CP and haven't left, I'm working in my dream role and couldn't be happier. My experience with the program was very positive because I knew I wanted to turn it into a career and sought out every opportunity to better myself. A few of my friends were like me and they are scattered around property in management positions now. The program is what you make of it. If you come down to party and have a good time, you will do just that. If you come down to work and advance, you will do that to; and have some fun on the side.
My advice, go through your training, be on your own for a week or two, let your peers and managers see what kind of person you are. Then, schedule a meeting with your manager and let them know what your goals are for the program. If you want to get into management, let them know. When a CP told me that, we moved him around to various roles and even made him a trainer, he went on to get a Management PI and is now and became a statused manager a few months after his PI ended. They are your best friend for something like this because most of them were in your position at one time or another.
If it turns out its not something you like, it's only for a few months, you get some work experience, and you get to put Disney on your résumé.
