Hi Stacy,
How exciting for you and your daughter! It sounds as if you will be on the go quite a bit so you will probably be dining at mainly Quick-Service venues rather than Table-Service locations. In general it is more budget friendly to eat at Quick-Service dining locations and it certainly allows for more flexibility since no reservations are required. Your total food cost will be dependent upon how many meals you and your daughter usually eat as well as if you will be ordering her food from the adult's or children's menu. I'm not sure which of the Disney's All-Stars Resorts you will be residing in but here is a link to the
End Zone Food Court menu located at Disney's All-Stars Sports Resort hotel. The other two Resort hotels, Disney's All-Stars Music Resort and Disney's All-Stars Movie Resort, have similarly priced menu and you can also view their food court's menus on the Walt Disney World website.
There are
Dining Services at ESPN Wide World of Sports Complex if your daughter will be competing at that location on the Walt Disney World property. Follow the previous link and you can view the food and beverage offerings at that location as well.
Stacy one tip I find very useful when planning a trip is to pack (or order through a grocery delivery service) cereal, snack bars, bagels, and dried fruit/nuts for a quick breakfast in my room each morning. Milk and other perishable items such as fresh fruit are also available at each Resort hotel's food court and can be stored in your hotel room's refrigerator.
Please let us know if we can help you with any further Disney vacation planning questions!
Blessings,
Brenda
