Hi, there is night bus can take you from the airport to People's Square at midnight. It is generally safe to take taxi at midnight from Pudong Airport.

Thank you, Ms Crystalring. Is the night bus the Airport Shuttle Bus? Does the bus stop at JW Mariott hotel?

I think you should take a taxi .It's safe .Normally the subway won't work at midnight .Taxi is safe .You can remember the License number of the taxi .Then you will be keep you safe by taxi .

We are trying to decide on a mini tour of Hangzhou & Suzhou. Is it possible to hire a taxi from the hotel by the day, say to take us from Shanghai to Hangzhou and travel around Hangzhou for the whole day, then catch a different taxi the next day to travel to Suzhou and around?

If you are going out to suzhou - take the train! It is fast, cheap, and safe. You can purchase "first class" or reserved seats at the station on the day of your travel. I think it was $20 a person when I used it. Then get a taxi in suzhou.
