Hi Yoonok,
Welcome to the Disney Parks Moms Panel.
There are several ways you can check your dining plan balance. You can use the
My Disney Experience mobile app. If you click on "Resort Hotel", you'll see all the details of your booking, then you can click on "Check Dining Plan". There you will see your available dining plan meals, snacks or mugs.
You can also call at the Front Desk of your hotel and ask for a print-out of your remaining balance. They will be happy to provide a copy of that whenever you need it.
Also, while you are dining, your server will be able
scan your Magic Band and can advise you what is still available on your Disney Dining Plan.
Here are full details of all the Disney Dining Plans.
Please come back and visit us if you have any further questions. We will be happy to help you plan your magical visit to Walt Disney World.
