Hi, Joseph, I just double checked the website, and it states that children must be 3 years old for their Fairytale Makeover at the Bibbidi Bobbidi Boutique. Click
HERE to see all the details. Appointments can be made by calling 407-WDW-STYLE (407-939-7895.)
I would suggest going to the Bibbidi Bobbidi Boutique located in the World of Disney Store in the Downtown Disney Marketplace. While your 3 year-old is visiting her Fairy Godmother-in-Training, your 2 year old can visit the amazing Princess Room in the World of Disney Store. Here, there are countless princess dresses, tiaras, toys, dolls, you name it! Perhaps she could do something special like the decorate your own jewelry box or create your own tiara while big sis is in her appointment. Some of the hairpieces and hair jewels they use in the boutique are for sale in this room, so perhaps she can make up her own look!
I hope your princesses have a magical vacation!
