I don't know how tall your 8 yr old is or how they like rides in general, but she might surprise you. Our daughter was 7 when we went last year, and her favorite ride of all the parks was Incredicoaster. In general, my kids prefer DCA over DL -not by much, but DCA is definitely their favorite. They have a much stronger connection to Pixar and Marvel than the traditional Disney movies. I think I'm the only one in my family that really likes all of the Fantasyland dark rides because they bring back memories from my childhood.
