I just read that you have to be over 16 to go on the Keys to the Kingdom tour. Does anyone know why this is? My daughter is 13 and very mature for her age. She would love to go on this tour. Since she can't go, we won't go. Besides, what is she going to do if we go for a 4 1/2-5 hour tour? She would just die if we got her a babysitter! Do they ever make exceptions for the age restriction?
