Expected to see much more, although the writing up of the cruise was quite accurate in the brochure. A lot of time is spent sitting on board a coach for up to two hours and the sights and excursions are all very, very samey. Food was only O K with some cold dishes being served at room temperature (e.g salad / a prawn starter) and the variety was quite limited, and fairly uninspirational. Portion sizes were, in general, quite small. No lunch buffet - the waiters were absolutely great but very, very overstretched. Meals were described by the Chef as "local" but we have seen the same meals on other Viking cruises. Evening entertainment was to 'care home' standard only. This is a cruise for those who don't mind being treated as children and seeing the 'same old, same old'...Company asks for suggestions but only take notice if money can be saved or if the suggestion meets with their initial approval. Great at saying "it will not work...". Have a suspicion that the Douro River cruise is run / directed by the local Portuguese authorities primarily to enhance the profitability of the local businesses and communities.
