If you're speaking about professional job, I would suggest that you go over to www.DisneyCareers.com and look up a few jobs that you might be interested in. Some require a bacherlor's or master's degree in any field, others are much more specific and require a degree in a specific field (engineering, finance).
If you're looking for a front-line job, a degree is not always required but it may limit the jobs into which you can transfer at a later time.
WDW and DLR are like small (or even medium-sized!) cities, requiring tens of thousands of people to keep them running. The types of jobs available is large and no matter what your eductional background, you would likely find something that fits it.
