I chose Emerald because the Emerald Star is only two years old and the tip for the crew is included in the total price. The ship was spotless and unseemly quiet. The crew pleasantly went out of their way to make sure all of your needs were met. The meals were always prepared correctly - meat not overcooked. And always a fine selection of different food types for all kinds of diets. The selection of local wines was an added touch that helped expand our understanding of the wine regions along the Danube The cabin was roomy and the full width window that opens was wonderful. The only shortfall was in the incomplete instructions to individuals that were not using the flight package in regards to boarding time. We spent two days in Nuremberg prior to the cruise and made it to the boat just prior to embarking. More time could be spent in Nuremberg.
