Hi Elizabeth,
Thank you so much for visiting the Disney Parks Moms Panel with your question! We love helping guests to plan magical vacations.
The
Epcot International Food & Wine Festival is a great event, offering so much to do centered on food and wine. The dates for this event for 2016 have been announced, and they are September 14 to November 14, so unfortunately, you are going to miss the beginning of the festival by about two weeks, and therefore the events associated with it will not have started during your stay.
I am sure; however, that you will have a wonderful time celebrating your daughter's birthday at Walt Disney World. Do be sure to pick up a Happy Birthday button for her, available free of charge at Guest Relations at the theme parks and many other locations throughout Walt Disney World. It will be so much fun to hear other guests and cast members alike wishing her a happy birthday!
Have a great time planning your magical vacation, Elizabeth, and please do let us know if you have any further questions.
