We just returned from a Viking cruise down the Danube, from Nuremberg to Budapest. It was a disaster. Here are highlights:
• The embarkation point was changed from Erlangen to Nuremberg (40 min drive) and no one told us!
• Two of the five cities we were supposed to see by boat were traveled to instead by bus.
Take the WWII special tour. It was excellent.
Interesting small city, but not great.
