I loved this ride in 2000 and loved it even more in 2004, but I am now 60 years old.
My 12 yr old granddaughter loved it as did her 36 yr old mom and her 32 yr old aunt.
If I were 10 yrs old, I am not sure I could handle it. I can remember being 11 yrs old and seeing the movie "Them" and then not being able to go to sleep cause I spent the night looking out my bedroom window to see if those giant ants were coming to get me.
Determining what is real and what is not for a 10 year old is still a little up in the air, so, if in doubt, leave it up to that 10 year old to decide. Never force a child to go where he (she) does not want to go.
