But not all were so lucky.
Here's the current status of some of the most important river cruise port cities:
Bratislava: The city is cleaning up areas of Tyrsovo Square, but by and large the city sustained no major damage.
Budapest: Budapest escaped any real damage after the Danube crested late June 9 and began receding the next day.
Melk: Sections of the historic Austrian town did flood when the Danube crested and cleanup is ongoing. The city's most picturesque attraction, the Melk Abbey, is undamaged.
Passau: The German city of Passau is thought to have sustained nearly 100 million euros in damage. Electricity and drinking water have been restored in much of the city and most streets also have been cleared of debris. All tourist attractions are open except the Roman Museum and the Niedernburg Monastery (also called Monastery Passau, Lower Castle)
Vienna: None of Vienna's major tourist attractions were damaged during the recent flooding.
Dresden: The Elbe crested June 6, and though areas of the city flooded, the historic areas were unaffected.
Meissen: Sections of this small historic German city were flooded but cleanup is underway.
Prague: All of Prague's main tourist attractions have reopened including the Charles Bridge and Kafka Museum. What cleanup remains to be done in the city is expected to be completed in about a week. There has been no long term damage to any sites.
