Thankyou Jiejie and Moondog. You folks are awesome.

If I leave 4 hours to deplane till check in to a hotel in Jing'an area, that would be around 6:30 PM. What would be your suggestion for a visitor to Shanghai at that time with 4 hours to dine and see? The bund? The temple will be closed but would it be ok to visit outside, take photos?
Is it ok travel to with a carry on and a computer bag in the bus? How much would a taxi charge from Jing'an to PVG, and how long would it take. I have the flight at 9 AM and must reach the airport atleast 7AM to reclaim my luggage at left luggage, hope they will be open then?
Thank you.
