I think the most important thing is to be honest and genuine. For example, Why you want to work at the Disney Store? Why are you applying there instead of somewhere else? Is it because you think the environment will be fun and energetic? Do you think it will suit your personality and that you might fit in there? The interviewer wants to find out if you're the sort of person who will succeed at the company. That's what you want, too. You don't want a job you'll fail at.
