My husband and I just returned home from a 5 night trip to Chicago. Having never been there before I signed up for the Greeter program which I found online on Trip Advisor. We only planned the trip a few weeks before (there was a "deal" on the flight), but the Greeter responded quickly. On our first morning, we spent about 3 hours with Nancy, with her showing us many highlights and some hidden gems. She also added her own information or history to what we were seeing and answered any questions. It just felt like you were with a friend who was showing you her city which she obviously loved. She gave us ideas of other places to explore on our own which we did the following days. She also went with us to buy our Chicago Architectural river cruise tickets (another "must do"). We did not use the CTA pass that day, but we certainly did the next day which was great.
