Based on one of Walt Disney's most famous and profitable films, Mary Poppins will make her way down Cherry Tree Lane and into Fantasyland at the Magic Kingdom. Replacing Princess Fairytale Hall on the east side of Cinderella Castle, Mary Poppins in the Park will bring the Edwarian London flavor to the Castle Courtyard, and compliment the other English derived stories of Winnie the Pooh, Peter Pan, and Alice in Wonderland inside the exterior castle wall.

The tenants of Princess Fairytale Hall will be relocated to their respective areas throughout the park, such as Snow White by the Seven Dwarfs Mine Train. The facade of the building will be re-dressed to resemble Cherry Tree Lane in England, and the interior queue will resemble the Banks Household, as you'd travel through the house before boarding your ride vehicles, which are old fashioned motor cars that seat 5 per vehicle.
