I recommend that you research the options based on your personal criteria (preferred chains, preferred spend, etc).
Are you flying or driving to Chicago? You will want to include parking in your budget of you will have a car. Overnight parking at many Michigan Ave hotels is over $50 per night.
FYI, you can find parking substantially cheaper by using Spot Hero. It's cheap and easy, just like me.
