Hi Cheyenne, and welcome to planDisney!
I am a big fan of
Disney Gift Cards and use them frequently on my trips to the
Happiest Place on Earth. One thing I will share is that as of when I write this, the
Disneyland Mobile App does not allow Guests to store a Disney Gift Card as a payment method. However, there may be a way for your siblings to still access the Disney Gift Card without you.
For example, if the card is an e-card, you can share the scannable barcode with your siblings by forwarding the email with the barcode to them. Whenever they are ready to make a purchase, they can pull up the email on their phone and present the barcode to the Cast Member for scanning. Another option, regardless of if the card is a physical gift card or an eCard, is for one of your siblings to add the gift card to their virtual wallet on their smartphone.
I hope your siblings find one of those options to be a convenient one. If they do, they can use the gift card pretty much everywhere in the Disneyland Resort, including one of my favorite stores, the
Emporium on
Main Street, U.S.A. – they have so many cute sweatshirts!
Best of luck,
Lola
