I am planning a trip in July to cover Hong Kong, Beijing and Shanghai for 9 days and am amazed at the difference in offerings from private tour companies. I have quotes starting at $4000 for 2 people for the full trip up to $20k from TCS Worldwide. I now have quotes from A&K, Wild China and Kensington. I have been reading quite a few not so great reviews on A&K who used to be the gold standard. Does anyone have experience with private tour company you can recommend?
