Thanks Marc and the Yangtze Explorer IS THE SHIP I would definitely use.
I loved Chengdu with the pandas and the changing faces show and good hotels there too.
Tibet - interesting I will check into that.
Guillin - that is worth a visit
Plus of course the Xian Warriors.
It is a BIG place and we will have to make choices. The cruises have allowed some to see Guillin, Xian, Shanghai and Beijing but of course there may be some who have never seen any of that. Always an issue picking and chosing between many options. Hard to do it all.
