I would say about half of the CP's take the classes. My university is pretty strict about getting credit for courses not taken at my university, so I could not get credit for any courses I took, but I still wanted to take a class. There are classes grouped under "Disney Exploration Series" which are more like seminars than actual classes (no homework, exams, etc). I took Disney History and I didn't like it all that much, but everyone else seemed to love it The way the classes work is that you get two days off a week (usually) and one of those days is your class. It gets to be a pain when your friends are going into the parks and you have to sit through class instead of going, but it's not terrible. Also they don't hold classes on weeks during the peak season (Christmas, holidays) because it is likely that you'll be needed at work.
