I can only speak for myself because I don't have children, but I've love Disney since I was a little girl. I can remember as far back as 10 but I have photos of myself at WDW with my grandparents from even younger than that.
I also wonder if male teenagers experience Disney different then female teenagers? Just an interesting thought. I find it's more acceptable for females at least in my experience growing up. It's acceptable for girls to still like princesses in high school but it would be odd for a boy to like captain hook and have captain hook things in his locker etc.
Yep, cause I just turned 40+ *cough cough* and I still love princesses. I think the older boys get, the more they get into the thrill rides & such (but I like those too).
