First, your guides and the drivers and their vehicles were all we could ask for. I liked the youth of the guides and if they are representative of the new China you have a bright future ahead of you. In Shanghai there was Teresa. A knowledgeable young lady who knew a lot about her city. She had no issues with our changing some of the itinerary. My only comment is that on the one full day she was with us she quit at 3:00. It really did not matter to us as we were more than comfortable going around Shanghai on our own. As it was we went to the Shanghai Urban Planning Museum at 3:00 and then made our way to the Mag-Lev train by subway and took a round trip to the airport on it. If I were to do Shanghai again, I think I would only employ a driver for the airport transfers. The rest can easily be done on one's own.
