could you please tell me the cost & time from Shanghai Airport to Hyatt on the Bund & also from the Bund into city via the high speed train

From the airport, you can take the local subway line 2 to reach East Nanjing Road Station and then change to take a taxi to reach your hotel easily.
The cost for subway is 7RMB per person and the taxi fare is around 15RMB.
The duration is around an hour and a half to two hours.
