I found out about this today while spending time in the Great Hall in Union Station. https://www.chicagot...xpressride.com/
There are quite a few kids wearing Christmas themed pajamas. It's really cute. I thought it would be something to do between the TE and LSL on my way back home but I saw the prices and I believe they are sold out most of the dates plus the times don't line up anyway and I'd feel out of date without kids. But if any of you live in or near the Chicago area and do have kids it's something to think about in 2018.
