I love that idea. It does seem like a natural fit. I have no idea how much those corporate sponsorships cost. I home schooled my kids so I always appreciated the educational aspect of the rides at Disney World. An exhibit at a World’s Fair might also be an effective educational / marketing opportunity, too. I do not know how it works at Disney but if it is the organizations, not Disney, that puts those things together it would be easy to create another version for the fair. Sounds expensive, though.
