Hi Alexandra,
There are two character meals where you can enjoy breakfast whilst being visited by the Disney Princesses.
Cinderella's Royal Table which is located inside Cinderella Castle at the Magic Kingdom or
Akershus Royal Banquet Hall which is located in the Norway Pavilion of the World Showcase at Epcot.
Your daughter would be made to feel like royalty at either one of these dining locations and the Disney Princesses will be happy to pose for photographs and sign autographs as they visit your table.
As these are two of the most popular restaurants at Walt Disney World, In order to avoid disappointment, I would highly recommend that you make advanced dining reservations at your earliest possible opportunity.
Reservations can be made up to 180 days in advance by calling (407) WDW-DINE or online
HERE
If for any reason you are unable to obtain a reservation, the Disney Princesses will be available for meet and greet at Town Square Theater in the Magic Kingdom.
Wishing you a magical trip!
