Wow some fascinating information here. We are going on our first river cruise of the Danube in June. Avalon Danube Symphony with 2 nights in Munich, June 19th - June 26th and then a train to Paris. I've been on the Rhine but this will be our first Danube. Will be watching the water level information though based on your comment above it sounds like we are missing the most troublesome part of the Danube. We will be cruising from Budapest to Vilshofen.
