GO SEE Millennium Park! It's in the heart of downtown Chicago and one of the MAJOR tourist attractions. There you'll see the famous Cloud Gate sculpture, which looks like a huge chrome bean. You also experience the cool interactive Crown Fountain, which is my personal favorite. If you arrive at the park first stop at the welcome center located at 201 E. Randolph Street in the Northwest Exelon Pavilion. There you'll find friendly guides that will help you plan your visit.
