Any thoughts about River Cruising and the best itineraries?
Yes, I am thinking about it, too. You will find a lot of information if you google Viking River Cruises. Check also: http://www.russiancruisecompany.com
We prefer Uniworld because they have bigger rooms & better bed configuration (hotel style). Took their Provence & Burgandy cruise a couple of years ago & will be taking one of their Rhine River Christmas market cruises in just 10 days! Check out their website in addition to Viking (similar itineraries). Excellent food (comparable to high-end ocean cruising), good shore excursions (walking tours of local towns usually). Intimate, easy way to explore a local region.
