Chicago travel tips
1) Live like a local in Chicago by renting an apartment or staying with Couchsurfing members | Airbnb and Craigslist are great ways to deal with your accommodation issue.

2) Spend time in The 606 trail in Chicago, similar to the High Line in New York | The 606 trail is very similar to New York's High Line Park. They are both created on abandoned railway tracks. It is customary to walk in this park and play sports. Sometimes festivals and musical evenings occur here. |
3) If you are going to visit many museums, buy the Chicago City Pass | The Chicago City Pass provides free admission to attractions such as the Shedd Aquarium, Skydeck, Field Museum, Planetarium or Art Institute and Museum of Science and Industry, or 360 Chicago. A ticket costs $108 and is valid for nine days. An additional bonus will be the priority line, i.e. you don't have to queue. |
