I' m arriving at 22.00 at Pudong, how can I get to Grand Mercure Central hotel? Thank you.

Well, the last schedule of the express train is 22:40. If you can catch it, take it from PVG to Longyang Road Station. It takes around 8 mins. And the fare is CNY 50 per person. After that, take a taxi to your hotel. The cab fare is about CNY 70 at night.

Or upon landing, take airport shuttle bus line 5 to get to Main Railway Station. The service hours of this bus line are until 23:00. It costs CNY 30 per person. Afterwards, walk west around 330 yards.

You can choose the way you like.
