Viking River Cruises does not offer fall packages through Europe. They do offer them in the summer though. Try a larger cruise line such as Princess or Carnival or Celebrity.
If you're thinking of a nice leisurely cruise down a quiet waterway, then a Viking River Cruise is exactly what you need. In each port along the route you are offered a guided shore tour. This cruise line is the largest river cruise vacation in the world with services to Europe, China, and Russia. You will thoroughly enjoy your peaceful, quiet vacation.
Some common cruise ships which are used in China River cruises are Viking River Cruises (Viking Emerald Ship) and Yangtze River Cruise with Victoria Katarina Ship and many more.

Viking river cruises are river cruises that are offered in Europe, Egypt, China and Russia to name a few. I am sure that they would be a wonderful experience, but I believe that they would be extremely expensive for someone living in North America.
