Hi Pamela!
Welcome BACK to the Disney Parks Moms Panel! Thank you so much for your great questions as you're not only helping your own family plan a super amazing Walt Disney World Resort Vacation, but others who have these question too!
The summer Quick Service promotion that you booked is new this year, and
Mobile Ordering using dining plan entitlements was also introduced recently. There aren't any stipulations that I see that lead me to think that you wouldn't be able to use your promotional meal credits when ordering via the
My Disney Experience App. But do keep in mind that at this time Mobile Ordering is offered at select Quick Service restaurants inside Disney's four theme parks and at one location at Disney Springs. New additions could be added to the list before your visit, so definitely check back.
At this time, Mobile Ordering can only be charged to Disney Dining Plans or to the card on file in your My Disney Experience App. While gift cards are not currently accepted for mobile dining orders, you can stop by the front desk of your Disney Resort Hotel every few days to pay off the balance of everything charged back to the card on file of your My Disney Experience Account or your MagicBand
using your gift cards.
Lastly, you are absolutely allowed to use your Quick Service entitlements however you'd like, including sharing a meal with a dining buddy. I like to do this so I can sample more snacks, especially when traveling around the
World Showcase in Epcot.
We'll See You Real Soon, Pamela!
