Hi there, Leon!
It sounds like you have a very magical day fit for a Princess planned!
I always like to allow up to 90-minutes to travel when using the
Complimentary Resort Transportation at the Walt Disney World Resort. I love to be able to slowly meander from place to place so I can look around and take in all of the wonderful details.
Since you're looking to enjoy
Cinderella's Happily Ever After Dinner at
1900 Park Fare after your
Bibbidi Bobbidi Boutique appointment, you'll want to be leaving Downtown Disney by 4:00 p.m. and at the bus stop for Disney's Grand Floridian Resort and Spa. In this case, I would make your appointment for the
Bibbidi Bobbidi Boutique at around 2:30 p.m. or so. That way, you'll have a little bit of extra time just in case they don't take you back right at your appointment time.
You'll be able to take a Disney bus directly to Downtown Disney from Disney's Art of Animation Resort - I recommend leaving your Resort by 1:00 p.m. You'll also be able to take a bus directly to Disney's Grand Floridian Resort and Spa from Downtown Disney.
I hope this makes sense! Thanks for sending in your question, Leon! Please let us know if we can assist with any other questions you have as you continue planning.
Wishing you and your family a Pixie Dusted vacation!
