We will be touching down Shanghai Pudong Airport in October about 3pm.

1)Should we travel from Shanghai airport to Hangzhou by long distance Bus or take a bus or mrt to the shanghai train station and travel by bullet train? Which is much easier and convenient?
2)I have hard time to search for a good and 3 star hotel for 3 person in a room which is near to tourist spot such as Lingyin temple, six pagoda, the west lake? Is Airbnb an alternative? Anyone can recommend a hotel stay or service apartment or airbnb apartment for only 4 nights stay. Best to near a supermarket to able us to cook for vegetarian meal.
3) How is the weather and temperature around 25th October?
