10.) DO download the My Disney Experience app.
With all those wonderful options for experiencing the magic at Disney World, it would be nice if you had a way of accessing all the latest information about the parks, characters, attractions, show times and more right at your fingertips. And apparently Disney World knew that—so they created the My Disney Experience app, available for download to your Apple or Android smartphone. The app is not only a tool to use while you’re in the parks, but it’s a great planning tool too. Use it to make FastPass+ selections and dining reservations, see restaurant menus, see maps of the parks and more. Make this download one of the first things you do when you begin planning your trip to Disney World.
