Disney Itinerary Cards
This isn't so much a how to, rather than sharing an idea.
I have the Touring Plans app on my phone, as well as MyDisneyExperience app. But being an over-planner AND having had a dead phone several times at Disney World, I decided to make quick touring cards that we could stick in our pockets for quick reference.
First I printed out each days itinerarys on stock paper. To make them, I just chose a large label template in word (3 inches by 4 inches, which is smaller once cut out).
