We were on the August 20 non-sailing of the Schumann as well. However, Dresden had so much going for it, that we made the best of a bad situation. We were disappointed not to be sailing, but overall we had great food, a nice clean place to sleep and we actually saw more in the 6 days there then we would have had we sailed. So if you want to have a lousy time you will. If you go with a good attitude you can still have fun. There were opportunities to go to the opera, several concerts, a city wide festival, lots of museums, stores etc. Don't understand why people can't enjoy themselves despite a bad situation. I found the staff to be helpful and kind.
