Back in Chi town

Just got settled down in the hotel in Oak Lawn. We tried to take a train, I thought we could but know I figured out there is a CTA trains, separate from Pace buses, separate from the Metra. So we need to buy another pass to ride it, so we can then ride in on the CtA trains. Pain in the ass if you tell me. Why isn't it just one system? We ended up just calling the hotel and getting a free shuttle to the hotel. Wish we would have done that the minute we got here. I think it's time to test the pool out!
