Just recently I was in a small discussion with a former New Orleans band member. He was vary bitter about the park and told me (a former cast member myself ) that when his contract was up he left Disney. he lead me to think that he was not wanted but gave me know clue as to why he wouldn't be asked to stay. he described Disney as "the wall mart" of theme parks and lead me to believe that his assumingly negative experience was standard for Disney.
so I wonder how the contracted deals with Disney work. are exceptional cast members asked to re-knew their contract or is their a continual auditioning process.
