Hi Allison!
What a great question! I can see where you are having a tough time, I took my daughter to the
Pirates League last summer and I was nervous she wasn't going to like it either. At the time she was four years old and completely in love with all things princess, and I was worried that the theming of the Pirates League was going to leave her disappointed. To make a long story short, my daughter loved it! The experience is absolutely wonderful, the makeup and hair is beautiful, and the Cast Members are truly engaging.
To make your decision, I think what you need to look at is what is important to you and your family. Taking all of your children to the Pirates League will be an experience that they can all share together for years to come. It will also be easier for your family, as you are all in one place, and all have makeovers at the same time, leaving you more time to explore Walt Disney World Resort.
If you are still unsure, show her pictures of the Pirates League and the
Bibbidi Bobbidi Boutique and let her choose. That way you will know she is going to be happy with the choice, and she will have a magical experience. A simple Google Search of "Mermaid Package at the Pirates League" will result in several photos of the end result of the Mermaid Makeover.
I hope that helps Allison. Please let me know if you have any other questions, while planning your Walt Disney World Vacation. I would be happy to help!
