We were a little concerned we might find a river cruise a little 'small' compared to ocean cruising but we should not have been concerned. It was a simply amazing experience - first class scenery, experiences, staff, food and company.
The excursions were wonderful - the Golden City of Salamanca, a wonderful concert in a church in Porto, the most amazing scenery. There was the chance to do more strenuous excursions if you wanted to.
The staff and the food were the best we have ever experienced on board any ship and all staff from the Captain down were very interactive and funny and nothing was ever too much for any of them.
Of course the cabins are smaller - otherwise we would not fit in the five locks up the Douro river! However, they were luxurious and the beds very comfortable.
The highlight of the trip for me was the photography. This was a cruise in partnership with National Geographic and not only did we have an expert lecturer Tim Weed, but also a photographer Gianluca Colla. He was patient, very funny, interactive and very tolerant of stupid questions.
The staff would join in - whether it was the head chef dancing at the lunchtime barbecue or the bar staff in the evening. The butlers did everything and were completely down to earth.
Beds were amazingly comfortable. The closet doors need some work as they were a little difficult to operate but that is a very minor point in an overall amazing experience. The cabins were always immaculately clean and tidy.
