My younger son will be traveling to Chicago for spring break with his high school marching band for 3 days last week of March. I am interested in planning to meet him with older son and husband for another four nights and I am looking for some suggestions to get me started planning. We enjoy off the beaten track tours, eating at local favorites not the touristy spots, museums, and outside activities. I assume the weather will be similar to Ohio weather late March..... Unpredictable. I am looking for moderate lodging with easy access to public transportation. I assume we will fly and not rent a car. I am surprised when I check Hotels.com how affordable the lodging is at that time! 250$ can get us some lovely hotels! Thanks in advance!
