Hi Tiffany!
Oh, your princess will adore her transformation at Bibbidi Bobbidi Boutique. Both boutiques will carry children's sizes 3 to 14, however I always recommend purchasing the gown from home ahead of time to ensure Princess style choice and size is not an issue. You can even surprise her with the dress when she awakes in your room, accompanied by a Royal Invitation!
You will need Magic Kingdom Park tickets in order to visit Bibbidi Bobbidi Boutique in Magic Kingdom. Park admission will not be required at the Downtown Disney location. Besides a bit more space to move around at the Downtown Disney boutique, there really isn't a difference to the actual experience.
It's certainly magical to be transformed within Cinderella Castle, but either location will become a treasured memory for both you and your princess.
Perhaps an Advanced Dining Reservation would be the perfect follow up to her day of beauty at either
Cinderella's Royal Table, Cinderella's Happily Ever After Dinner, or
Akershus Royal Banquet Hall?
I'd be happy to provide tips and details of each restaurant ... feel free to write us again.
Have a MAGICAL vacation, Tiffany!
