I am continually amazed at the markup the hotel imposes on this trip. I have never had a problem with a taxi from PVG. Get the name of the hotel written on a piece of paper in Chinese characters and then, ignoring all the touts inside the airport, simply proceed outside to the taxi line -- showing the driver the paper. The cost of a cab to the GH from Pudong is about Y170 or less, and it's just about as fast as the hotel pickup service (exactly the same if there is no line for a taxi, but there usually is a 5-10 minute line). It really isn't that bad, honest!

But if a cab really isn't your cup of tea (and you don't want to avoid them by doing maglev+subway+walking), I am sure one of the local residents will have some wisdom.
