Hi Amber, Thanks for visiting the Moms Panel! Your little Princesses are sure to love the Bibbidi Bobbidi Boutique, it is always a highlight of our trips for our little girls.
In the past when I have made Bibbidi Bobbidi Boutique reservations for two of my daughters, I have received separate confirmation numbers. The girls will each receive their own packet when they check-in. This will have a paper with "Princess ____" (their name) and the pamphlet to choose a hairstyle, etc. I have always wanted my girls to sit next to each other in the beauty-salon chairs. This way I can take pictures of both of them, and be able to thoroughly enjoy the experience of watching them both be transformed into a Princess. Otherwise, I know I'd feel torn and have to scoot back and forth across the salon to try to watch them both. You just need to let the Cast Member know when you check in that you would like to wait for seats next to (or close to) each other. The Fairy Godmothers-in-Training spend a lot of time personalizing the experience for each little girl and every make-over takes a different amount of time (based on hair style chosen, type of package, etc). Due to this, you may have to wait a little extra time for chairs that are close together. It is very worth it in my opinion.
You can make reservations for
Bibbidi Bobbidi Boutique up to 180 days prior to arrival by call (407) WDW-STYLE or (407) 939-7895.
I hope this helps and that you enjoy your magical vacation!
