The Wrigley Mansion is a fun stop as a tourist, though a little expensive for what it is. $15/person+$5 for one member of your group to become a trial member gets you a tour. We waited about 30 minutes and a tour of about 15 people was off. One of the coolest parts is the playing piano you get to see right at the start, but the house is fun and learning about the gum King is interesting. Our tour guide was great and seemed genuinely excited about the Wrigley family. The only knock on the place is we got a lot of "unfortunately we can't see that" on the tour because of private events and reservations going on. We just barely got to see the piano. I don't have any answers for that, but it made us feel like we were missing out. It is still a fun thing to do if you have the time.
