I will be attending the Madison tour next weekend. (YAY!) This will be my second tour, but the first tour that I will be taking my daughter to. She is 9 years old. My question is: Does she need a ticket also? Or do the tours work like some other places/attractions where kids under a certain age get in free? I know the tickets were free to begin with, lol I just need to know how many other people I can bring with me. THanks!
