My daughter doesn't even know who Harry Potter is as I suspect most younger children (she's 6). But she does know Snow white, Belle, Cinderella, Ariel, etc. I wouldn't take here on the Simpson's ride (I wouldn't let her watch it why would I want her to ride it?). I think US is a great park particularly IOA but when it comes to a family destination that we ALL can enjoy ....Disney wins every time. Even with the FLE. I think park attendance will continue to speak for itself!
