Congratulations to your daughter! I did the College Program at WDW in 2010 and it was one of the greatest things I’ve ever done. It is a job, so obviously there were some not-so-magical things about it too, but the good things far outweighed the bad for me.
When I did the CP, there were some options as far as taking classes. (Since it’s been 5 years, things may have changed - you or your daughter may want to do some research on the CP website to see how it all works now: http://cp.disneycareers.com/en/default/ ) I applied to the program and said I was interested in working Attractions or Merchandise. They offered me a spot in Attractions, and I accepted. I found out when I arrived to check-in that I was assigned to Kilimanjaro Safaris - yay! I worked that attraction the whole time and there wasn’t really any option to change attractions/assignments - what you accepted was what you got, unless there was a medical reason that you could not do what was required in that position.
My major was Anthropology so none of their classes for credit applied to me, but they did have classes you could take for personal improvement (no college credit) - I took Exploring Guest Service and Exploring Leadership and I really enjoyed them both. I was able to schedule them both on the same day, and if I remember correctly if you were signed up for a class you could not be scheduled to work at that time, so there were no schedule conflicts. I thought the classes were great - we learned concepts in the classroom with Disney higher-ups (managers, etc.) and special guest speakers, and then we took “field trips” now and then into the parks to see what we were learning in action. But again, you and your daughter might want to review the “Learning” aspect of their “Living, Learning, Earning” pages on their website to find out more about what’s offered for classes now, since it’s been so long since I did it.
Hope this helps! Congrats again to her and I hope she decides to give it a try! It was a great experience for me, and while I’m no longer working for Disney, my time in the College Program has come up in nearly every job interview I’ve had since then!
