Welcome back to the Disney Parks Moms Panel, Dawn! I'm thrilled you are planning another Walt Disney World Resort vacation and honored to be able to assist you with another magical question.
Your princess is going to adore her
Bibbidi Bobbidi Boutique experience at Magic Kingdom Park. I had a hard time finding recent pictures for the Courtyard Package, so I went ahead and called the Fairy Godmothers-In-Training to make sure. After listening to delightful Disney Park music, they informed me that the t-shirts are "Bibbidi Bobbidi Boutique" themed and the tutus are not particular to any princess, but rather match the shirt. (Historically, pink in color.) If she has her heart set on becoming Belle, perhaps you can bring an outfit from home or purchase one for her big makeover and reserve the tutu and tee for another park day!
My fellow panelist, Diane, just answered a question I thought may be helpful in finding where your daughter may be able to meet her favorite Disney princess.
Diane gives a great review of Belle's favorite and most frequent appearances in this answer. Have a fantastic vacation, Dawn, and as always, please let us know if there is anything else we are able to assist you with.
Magical Wishes,
Lauren
