Pros
Getting full-time status is hard no matter what department you work in. It will ultimately take at least one year; for me it took about 2.5 years. Before I made full time my schedule ranged anywhere from 14 to 28 hours per week. Moving up at Disney is hard to do unless you've got really specialized skills and experience. Most of their internal job postings all come with the taglines 'minimum 5 years experience', 'certifications in x, y, z, a, b and d required'. You really need to get enjoyment out of the work you're doing because the pay makes it difficult to be able to afford to do anything else.
Cons
Getting a good schedule takes seniority. A lot of seniority. In my department for example some people have worked there for over twenty years. Seniority is a double-edged sword especially for newer people. My biggest complaint is the pay though. Even the managers complain about how badly compensated they are. For example the latest cost of living adjustment one of my managers received was 3.4% and he's been with Disney for over 15 years. For hourly employees the biggest raise we ever get is ten cents.
