Among the FAQs of vistors to McCormick Place:
Am I allowed to bring my bicycle to McCormick Place?
Yes, you can bring your bicycle to McCormick Place. However, you are not allowed to ride it inside the building.
If you are going to Lake Michigan, you are allowed to enter the South Building and walk the bike through Level 1 and Level 2.5. At that point, you can access the outdoor sky bridge that leads to the Lakeside Center and then onto Lake Michigan itself.
Does anyone know how to do this without having to drag your bike up and down 2.5 flights of stairs?
