The Chicago Athletic Association was part of the Two Roads acquisition. And per the Hyatt Development page, it now looks like the property is officially being rolled into the Unbound Collection. Which that matches what the sales manager had told me and makes the most sense. She also stated it would be joining World of Hyatt by the first part of May.

Definitely another solid option for Hyatt in the Chicago area.
