Emily, I went there years ago when I was married and managed my former husbands office because the staff wanted to go for the holiday celebration event.
Personally, I think it is a lot of money for the show. I did not enjoy the violence.
As far as your kids are concerned, why would you want to introduce them to fighting and violence at any age? Better off spending you money going to see other things. Did you ever go to see the butterfly room in Chicago where live the butterflies are flying all over, land on you, you can see them close up eating. It is beautiful.
I don't remember the name of the museum, but it is across the street from the Lincoln Park Zoo's north parking lot - the street that runs parallel to the outer drive on the west side of the bridge.
There are so many things to do that are so much fun in and around Chicago. My grandkids have a blast going to the Botanical Gardens in Northbrook. We have been taking them every year for Mother's Day, Father's Day. We have lunch with the whole family also, or they have an ice cream shop across from a fountain where the kids can take off their shoes and walk in the fountain - when it is hot enough.
Have fun exploring Chicago.
