http://talk.collegeconfidential.com/forumdisplay.php?f=501 At least one Mom on there had her son get pulled out of his first week at college and into the WDW park cast of "High School Musical" (I know, but it's a job- to some people- and he got his Equity card, with all of it's pros and cons at that age). You can post or do a search and PM her. People answer VERY quickly with up to date advice there. Good luck! Go for it. The cruises pay pretty well, but you share cabins in shifts with other Cast Members.... Still,what do you have to lose? Let us know!
