I thought this was a very informative article about some wonderful river cruises in Europe. Can't wait for our next opportunity to try another one, that's for sure! Such an awesome way to see some amazing places.
The only disappointing part of the story was that they really only talked about Viking and Avalon. Of the 4 major river cruise companies, I would rank these two 4th and 3rd respectively. I believe that Ama Waterways and Uniworld offer a better experience, but there are also many others that are worth your consideration.
