This was our first river cruise where the service with Viking proved to be so outstanding that it is difficult to imagine how it could be improved. We traveled from the UK by Eurostar, such an easy way to travel to Amsterdam, delighted to find the ship only a couple of minutes walk from the Central Station. The quality of the food was excellent, wine provided, served by helpful and polite and engaging waiters. We enjoyed the company of people we have never met before, most of whom had already been on Viking cruises.It was pleasing to make drinks at any time on board. Five star accommodation in the cabin was excellent. Excursions were very interesting and each quite different, unique headphones ensured it was easy to hear the guides at the different locations, coaches ensured a minimum of walking and all in all the excursions were exceptionally well organised. Clearly Viking are the market leaders.
