Subway from Pudong Airport to hotel

Hi there,

Can you tell me how to take the subway from Pudong airport to the Bund hotel (525 GuangDong Road,Shanghai 200001,P.R. China). We will arrive around 8:30pm.
From the map, it looks like we can take line 2 to Lujiazui station or People Square station or NanJing station but we are not sure which one and how to get to the hotel from one of these stations. If we take a taxi from the airport to the hotel (in case the metro is closed) at night, do we pay a flat fare or by meter fare.

Thank you very much for any information you can provide
