Hello Tommy,
Character dining is such a clever way to see characters; they come to you, rather than waiting in line to see them!
The Princess Storybook Breakfast at Akershus Royal Banquet Hall at Epcot's Norway Pavilion offers guests an American style breakfast that will likely contain fruit, breakfast meats like bacon/sausage, scrambled eggs, potatoes, biscuits and cinnamon rolls. The princesses that are there do vary, but you may be able to see Belle, Jasmine, Snow White, Sleeping Beauty, and Mary Poppins.
Just an fyi, there are two other princess dining opportunities:
Cinderella's Royal Table (dining inside the castle at the Magic Kingdom) for breakfast, lunch, and dinner as well as
Cinderella's Happily Ever After Dinner at 1900 Park Fare at the Grand Floridian Resort.
Please let us know if you have any further questions. Wishing your granddaughter a magical trip meeting all the princesses!
