Howdy Laura!
I hope you are having a delightfully Disney day. Thank you for stopping by the Disney Parks Moms Panel with your Walt Disney World Resort planning question.
Unfortunately, it's been my experience the the Bibbidi Bobbidi Boutique is pretty strict on their age limits. Perhaps instead of a royal make-over with a Fairy Godmother-In-Training, your daughter would be interested in a magnificent mermaid make-over at
The Pirates League in Magic Kingdom Park? The Mermaid Package offers gorgeous, luminous mermaid eye makeup, a mermaid hairstyle and hair clip and more. There is no age limit for this experience and personally, I think it looks incredible. Although it's a little different, she'll still be treated like royalty and pampered in Disney style.
Have a wonderful trip, Laura, and please let us know of there is anything else we are able to assist you with.
Magical Wishes,
Lauren
