Hi Hank,thank you for your info.I still am not sure which hotel would I stay in Shanghai but will try to purchase train tickets on 25Sept.Initially thought of travelling back to Shanghai from Hangzhou on 30Sept by bus but worry that there may be traffic jam along the highway due to National day on 1Oct.Can you let me know is bus no 7 just next to Shanghai South Railway Station?and how do I get to Maglev station and continue to Pudong airport if I am early.
