My friend and travel companion took a week's cruise aboard Viking's
Primadonna in August 2011.
I think that that particular vessel has been retired, but Viking has also added at least a half-dozen new ships this year!
Viking is undoubtedly the largest - and, best - river cruise line going! While they began cultivating the European traveler, they quickly learned that the 'affluent American' is where the money is!
We were 99.85% satisfied with Viking. The 0.15% dissatisfaction ties into their ability to adjust to the American's comfort levels. In this particular situation: our American view of our walking capaity versus their European view of anyone's walking capacity!
As to expense: That is, of course, very subjective. However, my friend and I were hugely satisfied with the bottom-line we received, each traveling as singles. This is a matter worthy of considerable and detailed research! I urge strongly that you do NOT jump at the first offer, but, instead, study each offer thoroughly, then make a decision based on all 'best available' offers.
Once you have decided, resist every effort to change your mind, as such an action may very well - indeed, will most probably - change the dynamics of your booking dramatically!
As a former travel agent - long retired - as well as an inveterate traveler, I think that I have some expertise. I am always willing to share my thoughts!
