If she wants to ride, I would let her. The way I think its only a simulator, she cant fall out like on a roller coaster. I didnt think it was that bad, all the hype about feeling sick etc, I was fine. When you q up, you can see the pod etc, so she can get right to the point of climbing in, and still chicken out. i think its 4 people to a pod. Though they let us as a family of 3 ride together on our own. you each get a position,like chief bomber or piolet (spelling?) you are told when to shot or press buttons, this doesnt atually do anything or control your mission. OK ride, thought TT was more scarey.
