This is a premium charge for landmark drops. So if you're to travelling solo or as a couple, don't bother as you can be walk it off or use the CTA Chicago transit authority logistics. Personally had to a dreadful experience on 12/17. We were dropped off at the Navy Pier stop around 5:20ish. Expecting, per the bus driver's estimate of catching the bus either at 5:45 or at 6:12pm. We were back at stop by 6:07pm. Waited for the bus until 10mins elapsed in Chicago 's freezing cold. Then tried reaching the bus authorities on chat. So they don't have calling experience. The person at the other end seemingly checks with people on ground before responding. That takes time. By that time, you're bound to make other arrangements, lest you wait in the freezing cold for 20mins.
