You don't pay for the dinner in advance so if they don't have a enough people they'll call you and let you know....they hold the lunch everyday and if there's not enough people per day they will try to find you a spot at one of the lunches durring your vacation if they can.
Or, you can be an intern as part of the college program.
Kingdom WDW, do you know this for a fact?
Do they really have a few intern spot in the college program in Imagineering?
I know about the usual College Program in the parks, but they usually treat the people in the program like slaves.
