Hi Marci! Well, personally I think you're never too old to be a Princess...but as a mom to a daughter who's not really into pink (shocking, I know) I understand how you could be concerned.
I asked my 9 year-old daughter who she'd most like to dine with and top on the list was the evil stepsisters
Anastasia and Drizella from Cinderella, who join Lady Tremain, the Fairy Godmother, Prince Charming, and Cinderella herself at
Cinderella's Happily Ever After Dinner which takes place in the 1900 Park Fare restaurant at the Grand Floridian Resort. The stepsisters and Lady Tremain are very...entertaining...so I'm sure your daughters will be amused.
Another option if they are into Pooh, Piglet, Eeyore and Tigger is
Crystal Palace inside the Magic Kingdom and of course
Chef Mickey's in the Contemporary Resort features Mickey Mouse, Goofy, Donald Duck and Pluto.
If you check out allears.net under dining, click on the character meal locations and you can see which characters appear at which character dining experiences that might appeal most to your daughters. Enjoy your trip, whichever restaurant you choose!
