Greetings Wayne!
By the looks of it, you're planning a trip to the Walt Disney World Resort!
Here at the
Disneyland Resort in California, we don't have MagicBands but I'm very familiar with them and I think they're an awesome feature to keep things organized while on vacation in Orlando.
At this time, Disney Gift Cards cannot be linked to a MagicBand, however, you can charge all purchases and dining experiences to your credit card on file and pay your final bill at the end of your vacation with your Disney Gift Card(s).
In other words, although you may not be able to directly charge purchases made with the use of your MagicBand to your Disney Gift Cards, you can ultimately use the Disney Gift Cards to pay the entirety of your balance due.
I hope this helps.
Thanks for visiting the Disney Parks Moms Panel.
I hope you make it out to the Happiest Place on Earth in sunny southern California soon too!
