Hiya Nickie!
Welcome to planDisney! I had a chance about a decade ago to enjoy the Supercalifragilistic Breakfast at
1900 Park Fare at Disney's Grand Floridian Resort Spa and meeting Mary Poppins was one of the highlights. She is just splendid and practically perfect. I'm so excited a version of it is returning with the Strawberry Soup that I love so much. Unfortunately, you are correct, Mary Poppins does not seem to be included as a definite character set to appear.
I don't want to make a piecrust promise that is easily made and easily broken but I cannot guarantee that Mary Poppins will be appearing when you want her to. She does not appear to be a
character that is scheduled to appear. However, you have the best chance to meet her exploring the UK Pavilion in EPCOT. I would keep an eye on the
My Disney Experience Mobile App which shows character appearances. I have to say that sometimes, certain characters don't always appear on the app- especially if they are only going to be roaming through an area. I suggest on the day of your visit speak to a Cast Member who is a character attendant if they have any information about when Mary Poppins might appear. It is rarer but Mary Poppins has also been reported to be found in Magic Kingdom Park. I would stay near Main Street, U.S.A., keep an eye on the app, and speak to a Cast Member as well in the area. Good luck with sighting here!
If you are a true Mary Poppins fan then make sure to visit Disney's Grand Floridian Resort & Spa. You will find Mary Poppins inspiration throughout the dining room at
Cítricos at
Disney's Grand Floridian Resort & Spa. The resort is currently undergoing quite a bit of refurbishment but many rooms have already been transformed with even more Mary Poppin-inspired accents! Make sure to look at the chandeliers!
I hope you have a magical time! Remember, the whole world is at your feet so take time to explore!
Happy Planning!
