Hi, I will be in Hangzhou next November. My return flight is scheduled from Shanghai Pudong airport at 11pm. I'm planning on taking the train from Hangzhou to Shanghai, and then take a taxi to the airport. At what time should I leave Hangzhou in order to be at the airport on time? Is there any easier way to get there, like a bus directly from Hangzhou to Shanghai airport? Knowing that I will be with my wife, and probably we will have two luggages each. Thanks a lot.
