Of all the innovations coming to Walt Disney World along with the opening of Pandora — the World of Avatar, arguably one of the most interesting from a park-wide perspective is the introduction of mobile ordering. When the new land officially opens on May 27th, guests visiting Satu’li Canteen will be able to place their orders via the My Disney Experience app. As promised, this system will also expand to other quick service locations this summer, starting with Pizzafari, Flame Tree Barbecue and Restaurantosaurus according to the Disney Parks Blog.

As previously mentioned, only credit cards will be accepted in Mobile Pay as of launch and will not have support for any discounts or dining plans. Additionally, guests with dietary restrictions are advised to place their orders with a cashier.
