My wife and I made reservations for the Viking 2013 Passage to Eastern Europe (June 15 Budapest to Bucharest) cruise in August of 2012. Their brochure described a wonderful journey spending eight days cruising down the Danube and visiting venues we had not seen before. They particularly highlighted the Iron Gate area.
In addition to the monies paid to Viking we used many thousands of air miles for our flights. These miles could have been deposited back in our account had the trip been cancelled prior to leaving.
Due to extreme flooding on the Danube I checked with Viking regularly during the seven days prior to the departure date from Budapest both by phone and their online site. They said we would be notified if the cruise were to be cancelled.
Although we booked a cabin with outside veranda we could not use being tethered to another ship for six days.The cabin was OK, but very small.
