If you're looking for something like that, your best bet is to stop by casting or call the jobline (407) 828-1000 Monday through Friday, 8-8. If you call the Jobline, even when they're closed, there's a message that runs through some of the jobs they're currently hiring for, so you can get an idea where the big need is, but they're pretty much constantly hiring for entry level type jobs (retail, attactions, quick service, etc)
Most of the jobs posted on disneycareers.com are administrative, management, etc - they don't usually post openings for retail and such unless there's a huge need (they always post Magical Express openings, Photopass photographers, etc - must be a pretty big need for them)
