We want to walk across Brooklyn bridge when we visit at the end of the month and would like to walk from Brooklyn to manhattan. How do we get to the Brooklyn side of the bridge by subway? What station do we need to go to and how far is it from the bridge entrance? We have reserved tickets for the 9/11 memorial on the same day at 10:30am, do you think it's possible to do this walk before we visit the memorial centre in the morning? We are staying on 157 w 47st, roughly what time would we need to leave the hotel to get subway if we did it all before 10:30?
