Does anyone have any experience with Viking River Cruises from either Vienna to Budapest or Budapest to Viena. It's a 14-day trip with stops at Budapest, Pecs, Belgrade, Iron Gate, Bucharest, Constanta, Russe, Vidin, Orsova, Novi, Sad, Vulkovar, Kalosca, Esztergom,Vienna.
All suggestions gladly considered. I'll probaby post in the Hungarian and Romanian forums too. I'd like to see Eastern Europe before it becomes too much like Western Europe.
