Color-coded spreadsheet any three ring binder With all my room reservations dinning reservations with confirmation numbers, phone numbers and payment history. I also added in a list of all the menus for each of the restaurants we will be eating at along with closing times for all the parks extra, magic hours, fireworks and parade schedules.
Then there's flight and Magical Express info as well.
Did I leave anything out?

What's your planning technique?
