Ooo I like this idea. I have some off the top of my head. Some of which I know I will be accomplishing in January
Stay at the Grand Floridian
Get married at Disney World (I've always dreamed of this but I live in California and so do most of my family and all of my friends so I am not sure it would be worth them not making it. If not then
Disneyland!)
Family Reunion at Disney World
Trip with my core friends to Disney World (We take a trip every year to Disneyland.)
Eat at the Grand Floridian Tea Room
Visit new Fantasyland (Will do this in January!)
Swim in Stormalong Bay (Will do this in January)
Drink around the world (Will do this in January)
Visit every Disney park in the word. Especially Tokyo Disney.
Order a custom Disney cake and surprise someone with it at dinner.
I am sure there is more but this is a good start!
