Thanks, Kathy, for your comments.

We are not smokers and I am asking each company's policy pertaining to such.

Funny that you mention Viking. We received our Conde Naste today and Viking made the list of one of the best cruises. I will look into this line, as well.

The issue with river levels is a very big concern, as well. I do recall what happened last year and felt horribly for those poor people who saved and looked forward to their river cruises, only to have their cruises fall apart.

Lots of factors to consider and fortunately time to do so. While a river cruise seems really lovely and much more convenient/easy, I can't help but lean towards the possibility of a Tauck land tour. The only drawback for us with this is the packing and unpacking. But, a land tour is a great way to see much of the countryside and Tauck is a master at doing so.

I spoke with Tauck, Dielmann and Amadeus today and got some additional information on group pricing. Now I need to compile a list of pros and cons.
