Hi Orinda!
Thank you for visiting the Moms Panel!
As you have a 10.30 am advance dining reservation at
Tusker House at Disney's Animal Kingdom, you will be given 30 minutes to make your selection from the breakfast buffet, and then will be given enough time to enjoy your breakfast and visit with all the characters (Donald, and usually Daisy, Mickey and Goofy, although these are subject to change). Once your server is aware that you have met with all the characters and have finished your meal, you will be handed your check.
If you have any other questions, about dining at Walt Disney World, or other planning questions, please come back and ask me - I would be happy to help you plan your magical vacation!
