I'm considering the Yangste and sw tour. What's the main difference between traveller style tours and adventure style tour? Is it the class of overnight train travel. I'm comparing this with the Great China adventure which is adventure style but noticed this doesn't travel on local buses etc either? What is the difference in accomodation grading? I'm torn between a better value tour with Nanjing and Longsheng rice terrace trek... and Yangste river cruise, Kunming and less train journeys. Can anyone recommend the Yangste SW tour?
