After doing 3 previous Viking Cruises, we believed that this relatively new itinerary would be interesting and that Viking would provide a good experience and it did not disappoint on most levels. Hotels were in excellent locations, tours were interesting and gave great overviews of historical sites, etc. Busing from Prague to Krakow and Krakow to Warsaw provided adequate stops for snacks or stretching legs. In addition, bus trips always provided a stop in a town that allowed for exploration and lunch--good way to break up the trip, eventhough Viking buses are large and comfortable. Viking did a great job of breaking up groups into smaller, manageable ones that allowed for plenty room on the bus. Even had Polish vodka provided when the trip to Warsaw ended up being longer that projected due to traffic problems. Only real issue was the Viking representative who met us at the airport for departure--showed us to the wrong check in line and then disappeared on us even when he said he would be around to check on us. All in all, a great trip--so much to see and do and carried out with Viking efficiency. No water problems--fortunately, a whole day of heavy rains allowed us to go all the way down the Elbe even though we were given a warning a week ahead of time that the river could pose a problem.
