Thanksgiving in Chicago

My boyfriend and I will be staying at the Hilton Garden Inn Downtown Chicago from November 22-25. We have the entire day open on Tuesday the 22 but Wednesday (Thanksgiving) We are going to the parade at 8am. Then I would like to spend the rest of the day sightseeing. Like The Field Museum, Shedd Aquarium, John Hancock Building, and others. We plan to get most of these done on the same day because shopping is closed but most of the museums are still open. We plan on having the rest of the time to do whatever. I just need help on planning what to see and when and what can be left out.
