This was our third time River Cruising with Viking. And things got off to a rocky start with an estate room that smelled like sewer gas and the crew not doing anything to remedy the problem. The shore excursions seemed stretched at times like they had no idea how to fill the time. And then when they had a good excursion they rushed the groups and failed to factor in shopping or just walking around time. You need to read the fine print on every shore excursion with the Capitals of Eastern Europe!! The descriptions can be really tricky and many quests were not satisfied with the performance of Viking. I found that it was about 50/50 hit or miss on the excursions. The trip was very enlightening and culturally diverse but it is a one and done trip. Nearly all of the tour guides were amazing, very knowledgeable of the areas we were traveling.
