We chose Emerald Waterways having seen Jane Macdonald cruising on the same boat on her TV programme. The boat was very luxurious and the Portuguese crew were very attentive and friendly. The food was excellent - buffet breakfasts and lunches and a la carte dinners. Upon booking we asked about their inclusive drinks package and they gave us that for free. We enjoyed not having fixed dining times or seating, so we could join others as we wished for meals. We were fortunate in that the boat was only half full. The itinerary was perfect, boarding in the afternoon and not going anywhere until the morning. Next day we cruised all day til 4pm which made for a relaxing start. The scenery was beautiful, unless you don't like vineyards, and we were fascinated by the huge locks and low bridges for which the boat's bridge lowered, as did we! The excursions were good and well organised.
