I see that a lot of people's "Dreams" are about being able to buy/afford something that is readily available but out of their financial reach for whatever reason.
It's my read that Disney wants to offer experiences that money can't buy...Sleeping in Cinderella's Castle has never been offered, and can not be bought. Imagine the looks on people's faces when they're told they win that! Instant lifetime memory.
Here are a few of my Disney Dreams:
Ride Rockin' RollerCoaster with AeroSmith (apparently has happened before) and have them shoot a picture with us in the car before launch. Sit down over lunch with the boys from the band while they make prints and have them autograph the picture.
Spend a day with the heads of WDW and "chew the fat" about ways to improve the parks (e.g. real drinking water), theme park philosophy, and visions for the future.
Be invited to an Imagineering field trip when Disney is developing a new ride. The Expedition Everest special on the travel Channel showed a little bit of how they develop a concept, but imagine if you could be part of the process...
I'm sure if I thought about it long enough, I could come up with a few more, but I hope I'm illustrating my point. Think big when you dream.
