Hey there, Jann!
Welcome to planDisney! We're so happy to see you here with such a wonderful question. How very thoughtful of you to be thinking of your kids as they visit the Happiest Place on Earth! I hope that they're really excited for their upcoming trip and it sounds like you're adding some extra pixie dust to make it even more special!
I'm happy to report that you are indeed able to make a
mobile food order through the
Disneyland Mobile App without physically being in the Parks. In fact, I have seen third-party Disneyland bloggers use this as a method of rewarding their viewers who are actually in the Parks during a home live-stream. And to make sure that my information is current, I decided to place an order for a Rest In Chocolate Sundae (something I would ordinarily never do just for myself) at the
Gibson Girl Ice Cream Parlor and it allowed me to proceed all the way to the payment screen. You can then communicate with your kids about when to have the order prepared and then send them a screenshot of the confirmation code so they can pick it up! Just make sure that they can make it there within the pickup window or else the order might be cancelled.
I'm sure your kids will be so thankful to have someone at home thinking of them while they are enjoying a day in the Parks! I've sometimes given my kids a Disney Gift Card in order to give them some autonomy when making their purchases. It's important to note that you do have to be in the Parks and actually in the store to use
Merchandise Mobile Checkout, however.
Jann, I hope that my response was helpful for you in preparing for your kids' visit to the Disneyland Resort! I also hope that you'll be able to accompany them at some point, because it's a place "where parents and children could have fun together," as Walt Disney said himself. Please reach out to us again if you have any further questions. You're always welcome at planDisney! Until next time!
Wishing You a Great, Big, Beautiful Tomorrow!
