Hello Glenda and thank you for bringing such a great question to the Disney Parks Moms Panel.
What a wonderful vacation awaits you and your dear little grandchildren at Walt Disney World Resort, I can just imagine how excited you must be feeling!
You're quite correct Guests can indeed put spending limits upon their
Magic Bands; which is great for saving us adults from ourselves and our Disney shopping habits and importantly provides super safe spending powers for our young Mouseketeers!
I know from personal experience that it is certainly possible to add a card or cash credit to
Magic Bands with the help of a Cast Member at your Resort Guest Services.
And another thing; if the allowance isn't spent during your vacation then the left over amount will automatically get credited back onto the credit card linked to your
Magic Bands; how clever is that?!
If I can help further plan your upcoming vacation to Walt Disney World Resort please pop back to ask me another question.
Have a great Disney day.
