If you haven’t seen it yet, check out this fantastic viral video from Disney Parks & Resorts. Parks VP for Global PR Duncan Wardle told me the promotion paid for itself in about 18 1/2 hours measured by the bookings it generated. Since then, it’s been shared by millions.
Personalization, wow! factor and easy shareability were the keys. Be sure to watch till the end and listen for Goofy. This is cool stuff.
