Flight
I recommend flying into O'Hare International Airport! There are more airline options. For public transportation you can take the Blue Line. There are plenty of Ubers!
Flight
Midway is an option as well. It is further south. For public transportation, you can take the Orange Line. There are plenty of Ubers around as well!
Hotel
We aren't doing a hotel block since a lot of our guests are from in town. But here is a hotel that is about a 10 minute drive to the venue. The Guesthouse Hotel is an all-suites property with One - , Two -, and Three - Bedroom suites. There is a 3-night minimum over that weekend of the 7th.
Hotel
No hotel block here but this hotel is about 10 minutes from the venue. Don't forget to look at other hotels in Chicago! There are so many :)
