Besides the wait times, park hours, and park maps, Mobile Order is one of the most useful features of the My Disney Experience app!
Using the system in Disney World will often help you get your meals faster than if you waited in line, and it makes it easier to order when you can see the whole menu right there on your phone. A while back, Disney updated the Mobile Order system in the app to make it a bit easier to use, and when they did, they made a change that you probably didn’t know about!
