Me and my 10 year old son will be staying at the Marriott Suites ohare in Rosemont July 13-15. We have tickets to a cubs game Sunday July 14. The game is an 8 pm game I believe. Getting from Rosemont to Wrigley, we were going to take the blue line el and transfer to the red at Jackson and then to Addison. Getting back to Rosemont after the game at night is where I have my concerns. Do I just reverse my trip? Will the entire rout be safe? Will we be able to walk from the Rosemont station to the Marriott at night? Should we leave in the 7th inning and cab it back to Rosemont? Any other options? First time to Chicago.
