I am reaching shanghai pudong airport just right after midnight. How do I get to ssaw hotel?

Apart from direct taxi travel, you can take the Night Line of shuttle bus, which will not stop operating till 45min after the arrival of last flight. It is suggested to catch that to get off at Middle Zhejiang Rd (Yan'an Rd/People's Square) or Shimen 1st Rd (Yan'an Rd). Then take a taxi to your hotel exactly within 5-10min.
