Hello, Laurie!
By all means, your little 8-year old princess will most certainly not be the oldest princess at
Bibbidi Bobbidi Boutique. This very special experience is available for princesses up to the age of 12...and you will surely see girls older than your daughter getting their princess transformation while there!
However, should your daughter not be sure if she wants that particular magical makeover, consider checking out the Mermaid Package at
The Pirates League, over by the Pirates of the Caribbean attraction. This makeover is geared for any Guest over the age of 3, so perhaps your daughter will feel more comfortable with a magical makeover of a different color.
Nevertheless, if your little princess has her heart set on a Princess transformation, encourage her to go for it. She'll never be this young again, so it may be her last opportunity to be transformed by the Fairy Godmothers-in-training. She'll be so pleased with how special she feels not only during her transformation (the Fairy Godmothers-in-Training really know how to make a fuss over the princesses) but will continue to feel regal throughout the rest of the day. Guests and Cast Members will give your princess a very royal treatment as she wanders the parks looking spectacular. It's a wonderful day!
Best wishes coaxing your little one to enjoy herself at Bibbidi Bobbidi Boutique! However, should she choose to transform into a Mermaid, she'll still have a wonderful experience, and you'll get some great pics, too!
Please send more questions as you think of them; I'd love to help!
