So I'm trying to decide between a Russia-Siberia land tour and a Russian river/canal cruise on the Viking Kirov. The Viking Kirov package sounds reasonable, but I'm seeing a lot of negativity on this forum wrt Viking River Cruises. What's the real deal? I've enjoyed everything from Crystal to Holland America, but I don't want to disappoint my sister who's a first-time cruiser. Is this Viking Kirov cruise
an OK deal?
