We booked with the knowledge of the low water condition so were not at all surprised that the ships remained moored. However the use of two identical and new ships as floating hotels worked well. Everything was to the Viking standard we have come to expect. This was our fifth Viking cruise.
Wittenberg's reformation history, and the fact that our travel was in what was once the Eastern zone, made this a very educational cruise. The fact that the ships were immobile detracted very little. Also, Viking upgraded our booked Standard cabin to a Veranda cabin and provided us each with a $1,000 voucher for a future cruise.
We also took the post-cruise extension to Krakow including a day trip to Auschwitz. The city of Krakow was delightful and our Viking hosts handled the Auschwitz trip with professionalism and true sensitivity - we are very glad we visited Auschwitz but it is not an excursion one would make twice.
Although we had booked for a Standard cabin, we found that Viking had upgraded us to a Veranda cabin. The cabin was quite comfortable and (obviously) efficient. Cabin housekeeping also was excellent. Again, thank-you Viking.
