We have rated this low because of the incredible length of time 4 hours to get to Hangzhou in a tiny little cramped mini-bus, no good if you are tall! The tea gardens were very interesting but of course, the usual hard sell with increased prices for Westerners according to our Chinese friends. Hangzhou was incredibly polluted, as is much of China of course, therefore very dull and extremely hot in September. The drive back to Shanghai was interminable and increasingly uncomfortable. Sadly, we would not recommend this trip. The day trip to Su Zhou is much better!
