Hangzhou day trip or overnight - prior to Beijing
I’m staying in Shanghai from 9-13th October prior to going to Beijing via high speed train from 13th-18th October. I’m planning a side trip to Hangzhou mainly as a city escape to see the tea fields. Is it better to remain based in Shanghai & do a day trip out to Hangzhou say on 11th or 12th October? Or is it better to stay overnight in Hangzhou 12th October & then catch the high speed train to Beijing from there?
