June 2016 - Viking Njord to River Cruises - Europe
Overall, the staff was very good, although some additional variation in the food offerings and canned music in the lounge would have been appreciated.
Also, owing to high water (v. bridge clearances), the upper deck was closed for about three days. I think we and others felt cooped-up, and couldn't quite understand why sections of the upper deck weren't made available when we were docked. Assume there was some valid reason.
Walking tours tended to be longer and tedious, especially for older folks.
Having said all this, we would probably consider going on another Viking cruise although we would plan a bit more about what we might do on our own when making shore visits.
Two days in Budapest prior to cruise were great, as was the local host!
