I just got back from a 20 day trip to China using China Discovery Tours. Do NOT use this company. Some of the guides did not speak English. half of the restaurants were either filthy or inedible. They charged me an extra $200 per person for a non-shopping tour and then took us to a Silk factory, a jade factory and tea factory. I booked extra tours that I was charged for and they were shopping stops rather than the tours I asked for. I could go on, but won't. When I contacted them upon my return, they gave me a lot of double talk, refused to reimburse the non-shopping charges and offered me $100 toward my next trip with them. There will be no next trip with them. I would be happy to elucidate if anyone needs. I just wanted to be sure to get this out to the public. When I was booking, I couldn't find any reviews of them on TripAdvisor and wanted others to be able to benefit from my experiences.
