Yes, I agree it's an easy walk w 1 rolling bad and a briefcase from the "subway" (actually overhead rail at some time)...I would say 5-7 mins. I did it multiple times without luggage .

I didn't understands the subway system. There are no turnstyles. You can walk off and on for free. There are roving inspectors who will give you a steep fine if you don't have a ticket .

It took me a few times to understand this system .
