We were on the Eurodam 21-28 December. Chele68 has positive comments above. Our comments differ. We thought the food was just so-so. The entertainment is below standard. There really are not any "big" shows with singers and dancers on the Main Stage. The dancers are good, but the overall performance (sound, choreography, stage design, etc) is well below what you will find elsewhere. We at first thought the two piano player/singers in the lounge near the casino were amateurs who had been given a chance to perform. They played all the old songs, so people loved to sing along, but their musical/singing skills were not great.
The crew was fantastic; everyone friendly and helpful. The ship is old, but is in pretty good shape, although a water leak flooded our hall and kept things wet for about 3 days.
We have decided to try the new Rotterdam to see if there is a better product. Otherwise, we will switch to another line. We had a good, not great time. Cruising, at least on Holland America does not appear to be what it was just a few years ago.
