Dear Rada,
Thanks for contacting Top China Travel!
Usually we call the route from Yichang to Chongqing is Upstream, and from Chongqing to Yichang is Downstream. It is almost the same to start from Yichang to Chongqing or Chongqing to Yichang. The biggest difference is downstream takes less time. Upstream (from Yichang to Chongqing) takes 5 days in all and Downstream takes 4 days in all. The attractions along the Yangtze River are nearly the same. Usually there are only a few minor differences for shore excursion programs between ships of the same company and most ships will have exactly the same programs for both downstream and upstream cruises.
Any further request or question, please feel free to contact with us.
