On number 6. If you're referring to "Traditions" that is a very prestigious goal to achieve at WDW. The biggest challenge (assuming you are chosen at your audition) is remembering content. I teach at DU part time, those positions are treated as "shows" and like a show yet have to remember your lines no books, cheat notes etc. My show notes for the course I teach is 72 pages all memorized. From audition through training and finally your "check out" was close to six months. Some like "Traditions " take longer. Also facilitating "Traditions " is a once in a lifetime opportunity. If you are chosen you can teach for one year and one year only! Even if you leave the company and come back you came never teach Traditions again.Any of these would be fine:
1. An idea man, not engineering or implementation, just concepts and ideas
2. A park ambassador that just wanders the grounds, answers simple questions, and greets guests
3. The person who picks the background music
4. Main Street horseless carriage driver
5. Train station platform worker
6. Teacher/trainer of the Disney 101 course that I've heard everyone had to take
