My family (me, my husband and four young kids) will be in Utica, IL Wednesday and Thursday and are looking for recommendations of other family locations/activities within 2 hours of Utica. We originally could not stay through the weekend but plans have changed and our hotel in Utica has our room booked already so we will be heading somewhere else on Friday. Thought about downtown Chicago but have ruled that out. Any other suggestions? We live in central IL but have never traveled north and this trip is very spur of the moment.
