I would like to visit suzhou and zhouzhuang for a couple days before catching a flight from Shanghai Pudong to return to US. The returning flight from Shanghai is at 11 am on a Saturday morning (4/24). What would you advise, should we stay the night at zhouzhuang or Suzhou and leave early in the morning for Shanghai airport? Or should we go to Shanghai the night before? Between leaving from Suzhou or Zhouzhuang, which one is preferable? And what transportation is advisable? Thanks
