Hello Sara!
Welcome to the Disney Parks Moms Panel with a great question!
Cinderella’s Royal Table is considered a signature dining venue, so many Guests wonder about the dress code to dine at this great restaurant located inside Cinderella Castle. Character dining does not get any more magical than this, but do not worry about a strict dress code. While little ones are encouraged to dress up to the occasion, the restaurant is located inside Magic Kingdom Park, so adults are welcome to wear their casual park attire.
Last time we dined there my husband was wearing shorts and a Hawaiian shirt, and I was wearing jeans and a t-shirt. We were both wearing tennis shoes, and our little girl was wearing her favorite Disney Princess gown. If you don’t feel comfortable dining in casual attire, you can always bring different clothes or maybe a different top, for example, and change.
Thank you for bringing your question to the Disney Parks Moms Panel, Sara. I hope this helps you while planning and that you have a fantastic time at Cinderella’s Royal Table.
Best magical wishes,
Thiana
