Marc - I was wondering the same thing. You'd think Viking would incorporate all of their KD cruises into their Viking brochure. Maybe they'll do it next year. Viking is mentioned in the KD brochure, right on the front page. They suggest choosing a Viking cruise if you are looking for a longer vacation.
I'd love to do a longer cruise, especially since we'd be coming from so far away, but it's impossible for my husband to be away from work for more than 11 days at a time. In fact, 11 days is 'pushing it'. Your cruise sounds wonderful!
My husband's family was from Bavaria and mine was from Alsace and Switzerland, so this trip will have some sentimental value for us too. Thanks for your opinion about KD. I really appreciate it!
