This was our fourth river cruise and fifth cruise overall with Viking. Although we had a couple difficult nights at first with the air conditioning in our stateroom, the crew on this trip has been the best we have dealt with of all our Viking cruises. We took the Rhine cruise last year starting in Amsterdam and terminating in Basel. That cruise was probably our least favorite due to the low depth of the Rhine causing us to change ships midway near Koln and losing an entire day on a bus, and ultimately coming home with Covid. The Tulip cruise took us to places we had not previously seen in Belgium and was a great experience. The most noticeable thing about this trip was the comfort the crew had with the guests. They were very interactive, they quickly learned names and addressed you as often as possible. In all the trips we've had, we've rarely seen the Captain, but in this trip he appeared in the lounge every night, engaged the guests and even stepped to the dance floor with a few. While on board, you felt like family and although that's not the point of the cruise, it certainly makes your stay more of a joy. Seeing the windmills and tulips are great, and that's an obvious given, so there's not much to say about that. When traveling on Viking, even the worst trip we've had was still an incredible experience. One additional thing we noted this trip was the fact that this crew wanted us to share our experience with Viking, the good and the bad, so they could improve their services. They encouraged us to share our complaint about the room issues and Viking actually called us before we called them, which indicates the crew had notified them in advance. This displays a higher level of responsibility towards the guest than many types of business practices routinely display. Our cruise last year was all about not "blaming the crew" for a poor experience. Traveling on the Sigrun was all about being the best and striving for perfection.
