Traveling to Chicago in a few weeks with two teenage girls and their moms. We'll be shopping during the day, but am looking for something affordable to do Saturday night. We live in a very tiny rural town in Michigan, so I want to give them a unique big city experience. There's nothing on the calendar for Navy Pier when we're there. I have never been to Chicago in the winter, so I don't know if Navy Pier is worth the trip then or not. Not interested in the ice skating options as we live on a lake and can do that whenever we want. Thanks for any tips!
