The tween years are fun. I find that DD(11) is both younger and older at Disney. I make a conscious effort to let her exercise some new found independence in a safe environment (making purchases, riding some rides alone, being the "runner" if we need something while we are waiting on a parade/fireworks/etc.). She wants to get her hair done at Bibbidi Bobbidi Boutique, but she wants to wear her own fancy dress rather than looking like a Disney princess. She also likes to be part of the planning and pick restaurants and experiences herself. Believe it or not, she always picks Les Chefs de France, because she wants to order their escargot, and she has been asking to go over to Universal next time to see the Blue Man Group.
Does she have a favorite character? DD isn't at all interested in waiting in line to meet characters, but she enjoys the character meals and if we come across a character with little or no line, she wants to meet them. Since she loves Stitch, I make sure to always plan a breakfast at 'Ohana.
DD also loves rides, and if it was up to her, she would pick a ride for the day and do it over and over and over again. I don't know if that is a tween thing or just her personality.
