I will try to stay on matters relevant to prospective travellers and not to dwell on incidentals. A few specifics that may set a framework: we travelled from June 20-July 5, 2013, from Shanghai to Beijing with extension to Guilin and Hong Kong; Im 68, overweight, but long ago athletic, and my wife is 57, not athletic, but generally fit. I wont try to cover everything but will focus on pros and cons, each in chronological order.
