My wife and I arrived in Budapest 4 days early to explore that beautiful city on our own, so, of course, our first contact with the Viking staff was when we boarded the Njord. From the first moment we were treated with great care and consideration. The taxi driver let us off at a different Viking ship but the crewman from that ship walked us down to where the Njord was docked and even helped with our luggage.
The cruise itself was great, especially the fabulous meals. The crew (from the Captain, the Cruise Director, the Head Chef, waiters, concierge, housekeepers, and all the rest) were friendly, efficient, and very helpful. We enjoyed the excursions and the free time to explore the cities along the river. Our only complaint was having to get up at 3:30 am to get us to the airport for our 6:20 flight. But we've had to make early flights before so that was not a big deal. Overall, we would highly recommend this cruise for anyone. We're in our middle 60's and not terribly athletic but we had a wonderful time.
