polish expo transit options

Is anyone else going to the polish and beauty expo from Chicago? My friend was going to drive me but isn’t going to be able to come so I’m asking other friends but wanted to know if anyone knew of transit options to get to Tinley Park (shuttle, trains, buses) or if there are any carpool groups?

I just requested to join the FB group so I will ask there too but wanted to check here too as they haven’t processed my request yet.
