I didn't take any of their classes while I did the CP. It's different for everyone, but for me, it was an excellent way to stall for time. I was a freshman in college (community college) not settled on a major, and while the CP didn't earn me college credit, I earned alot of /life credit/. (Working for a big company isn't all sunshine and rainbows, but its ten times better than mcddonalds, and I know because I was working with fast food at Disney and serving happy and unhappy people alike!)
If you're smart and not spending your time getting plastered, you get experience with time management, a whole load of general professional skills, social skills (my roomates were pretty much ew...) and they offered alot of activities and sort of 'hands on lectures' by Disney higher-ups. Obviously geared more towards those wanting to get into communications, HR, and such, BUT...inadvertently, my time spent down there is responsible for pushing me towards art, which led me to art school, which is awesome.
Like I said, its not the same for everyone, and I consider myself very blessed to have had a pretty good experience. I've talked to people who hated it, and people who loved it, and people who thought it was okay. I would strongly recommend it for freshman/anyone who is floundering and in need of career direction, unless you have the money and time to take a few months off school to party.
Also, by doing the basic college program, it gives you leeway into their Professional Internships, which is more focused for your own interestsl marine biology/zoology at Epcot/AK, the obvious business choices of course, graphic/internet/game design, marketing, television...ALOT of stuff. And if nothing else, a pro internship will look really good on your resume. I'm hoping to land one myself in about a year.
What did you expect, a short answer? I'm a darn Campus Rep for the Program.
Hope this answered your question, Andrea!
