The trip was great in every respect. Crew were all helpful and pleasent. The food was all good and and a variety. The trips of the boat were interesting and guides gave us sufficient information. The trip up the Douro was the best view I have seen on any river trip. The passenger were from vareous destinations, which made for interesting conversations. The meals were sit where you like which helps to make it more interesting than being with the same people all the time. Travelling through the locks was very interesting as I am a Chartered Engineer. There is a lock which rises about 100 feet. It was an unbelevable experience.. The boat was very clean and every thing in good order. The only slight problem was that all the wall s and columns were stainless and lik mirrors so it took a little while to get use to seeing one self when moving arround
