6. Check Wait Times with the My Disney Experience App
Did you know the Disney Parks have their own app? That's right, it's called My Disney Experience, and you can use it to check wait times, reserve or change FastPasses, locate attractions on the map, see that day's showtimes, and more. This is a very handy tool to keep on your smartphone as you traverse the parks.
Pro tip: Since you'll be checking this app a lot and taking pictures and such, bring an external battery pack or charging case to keep your phone juiced throughout the day.
