...well how about packing a big bag with clues - items that begin with a "D", an "I", a "S", an "N", and so on, but give them the item (or picture of the item) in a 'jumbled way', in other words not the "D" first, followed by the "I", etc. and then they have to unscramble the letters...of course, I don't know if your kids are too young to do this...
...another version might be to give them Disney-themed things to do, like a WDW coloring book or activity book, a Disney puzzle, request WDW park maps and have them circle them things that they REALLY want to do, sorta like THEM making an itinerary, etc....
