We left Budapest on October 5th and after a relaxing day of cruising, we arrived in Vienna around dinner time on the 6th. We were very fortunate to be able to navigate this stretch of the river; I believe that some cruisers had to be bussed to Vienna the next week. We enjoyed a day and a half in Vienna and when we boarded the Expression around 8:00pm on the second night, we found a letter outlining modifications to our itinerary that were being made due to low water concerns.
In a nutshell, the changes (for the majority of passengers continuing on to Prague) were
1). Linz, Austria was substituted for Nuremberg
While compact, the cabin's design gave us plenty of storage, a small sitting area, and beautiful views from our "window wall"
Bathroom was very well designed with generous shower stall, excellent toiletries and storage for personal items
