Hi, I'm looking for help on which subways to get. I've researched this and checked out the maps but really unconfident. I've visited once before and walked everywhere but this time I am taking my grandad who is 80. He's fit but we will need to use the subway. We are staying w.47th so I just wondered where the nearest subway is to get to these places: battery park, Museum mile, Greenwich village and cony island.
Please help and thanks :)
