Sailed from Bucharest to Budapest; visited former Communist controlled countries. Many of these countries are struggling, still, due to corruption in governments, unemployment, little to no infrastructure, etc. However, found people were wonderful. It was depressing to see so many "left-overs" from the Communist regime, i.e., falling-down buildings, little to no new construction or housing, etc.
Cruise ship, Elba, is one of the new long ships. She was beautiful. But, we have been cruising with Viking since 2005; this was our 9th cruise, and we have found, that over the years, Viking has changed, some to to better, some not so much so. In the beginning, there were smaller ships, much FEWER ships on the rivers, and we felt like a part of the Viking family. Staff, in the beginning, interacted more with passengers, and it was more fun. There were fun activities on-board with the crew. In fact, we have since sailed with some crew more than twice. We have seen a definite difference in how the crew and staff are allowed to interact with passengers. One instance, one of the staff wanted to show us a picture on the cell phone, but he said he had to be careful not be seen doing this by his "boss." This would not have happened in the beginning.
When we docked in Budapest, I personally counted 17-different cruise ships docked. In the first few years, we were lucky to see one or two ships docked at our same location, and more often, they were Vikings.
