re: Chicago...staying around Miracle Mile. Still a good idea?

This may be useful to people asking this same question:

Time Out: Where to Stay Best Areas and Neighborhoods

So far, from reading various threads (thanks to everyone who posted), I have this tentative plan for our one day to explore the city.

Arrive midday at Ohare, leave luggage at hotel (in Rosemont), take either blue line or Uber to downtown. Visit the Art Institute and Maggie Daley Park area, walk the river walk, take the red line to Fullerton(?) to see Lincoln Park. Afterwards, walk Fullerton up to Halsted just to see the neighborhood, take a cab (still have those?) to ZaZas pizzeria on Clark (we don’t want Chicago style pizza and have seen good reviews of ZaZas, but open to suggestion). I think that would leave us with finding one more thing to do at about 6 before we Uber back to Rosemont, so what would you hypothetically do at that time of the day with your teenage kids who have never been to Chicago? We were thinking of a tour of Wrigley but there doesn’t seem to be enough time.


See any issues with that plan or am I missing an obvious better use of the time?
Obviously I’m trying to compress a lot into too little time, but tell me if something seems way off.
Would you be worried about the safety of the blue line from Ohare to downtown in midday?
Is there a particular section of the river walk you recommend?

It’s supposed to be in low 60s with a 10 mph East wind with a rain possibly. How cold is that going to feel to South Louisiana folks?
I know we shouldn’t wear shorts, but do we need jackets/hoodies IYO?

TIA

ETA: I guess I left off walking the Mag Mile. Could take the Riverwalk to Michigan and walk north, to loop that in before going to LP.
