You might skip the beer in favor of the Franconian wine
Bite your tongue!
With a username like mine, surely you can't be serious.
Actually, the Franconian beers are also unlike other Bavarian beers (but equally wonderful in their own way).
Our cruise will be on the Mosel, Rhine and Main rivers, so enough variety.
I'm extremely familiar with Munich, Bamberg, Cologne, Frankfurt, Wiesbaden, Garmisch, and a few others, so Germany is always a relaxed visit for me. This tour will provide a number of new cities I'm looking forward to.
