Travel
Here are some suggestions for those of you coming into town!
O'Hare (ORD) and Midway (MDW) are the main airports, both are similar distance from the city and have trains that go to the Chicago Loop (city center). The Orange Line services Midway, and the Blue Line services O'Hare.
We did not reserve a hotel block because everybody has their own preference and Chicago certainly won't run out of rooms :) Below are a few suggestions for nearby hotels. The Holiday Inn is just two blocks away from the wedding, and the other two are a 5 minute uber, or a 15 minute walk away.
