I think it's important to head off to college when you think you're ready to. If that means taking off a year to work, to travel or what have you, then that's absolutely fine! You only live your life once, and if taking a break from school helps you to focus that much more on your studies later on, then that's a respectable thing.
Of course, there are tangible benefits and transferable skills that you'll gain out of a Disney experience, so that's a plus too. It sounds like you're trying to plan out your future - and such is not the hallmark of an unwise person.
