I am planning to take a train from O'hare airport to downtown at midnight. The hotel name Blackstone Renaissance Chicago Hotel.
This is the first time I am going to Chicago and I am not familiar with the train system. Is it safe to take a train around that time? I will have a carry on bag and a small backpack.
If it is safe to take a train, then what is the best way to go to the Blackstone Renaissance Chicago Hotel?
