Hi Diana,
Absolutely! Your whole family can experience
The Pirates League together. Four of my kids joined Captain Jack's crew last October. While we were there, we saw several parents getting the make-over with their kids. It was clear that they were having a blast making memories as a family.
In regards to your little girl, my youngest 2 daughters have enjoyed
Bibbidi Bobbidi Boutique on 3 different occasions. This last trip they decided to try The Pirates League instead like their brothers. There is a "Pirate Empress" make-over which they both picked. The make-up is similar to Bibbidi Bobbidi Boutique, and the Pirates do their hair too (just not as fancy as at the Boutique). In addition, they get their nails painted and receive a pretty face gem too. My girls truly enjoyed this experience. Granted, it's different from the Boutique, but I think if your whole family is doing it then your little girl will have fun too.
Hope this helps and that you have a Magical vacation with your family,
Kaylene
