Hi Maria!
How exciting that your princess celebrates her birthday on the day of Rapunzel's coronation!
Disney is planning a "star-studded, worldwide celebration" for this big event, which takes place at Kensington Palace in London on October 2nd! You can read more about it on the Disney Parks Blog, by clicking
HERE.
At this time there has been no announcement of any special events happening at Walt Disney World on that day. However, I did hear that after Rapunzel is crowned in London, she will begin wearing her official crown within the Walt Disney World Parks as well.
Through the magic of Disney, Rapunzel appears in Walt Disney World every day. She can be found at the Magic Kingdom with Flynn Rider and Pascal at a special "Play & Greet" in the whimsical Fairytale Gardens near Cinderella's Castle every day. Check the daily Magic Kingdom Park Times Guide on the day of your arrival. Also, she has been spotted, and you can visit her beautiful tower, at EPCOT at the Germany Pavilion!
Please continue to check back at the Disney Parks Blog on a regular basis to see if there are any more announcements regarding special events for Rapunzel's coronation, and I wish YOUR beautiful princess a very special and magical birthday!
