We loved the Zuiderdam. We were in cabin 1121 on the main deck, and that worked out great for the three of us. Although we didn't have a veranda, the view out the large window was great. There was plenty of storage, the water in the shower was always hot, the toilet always flushed and we never had any funny smells. My mom was in 6068, and I thought her cabin was spectacular. It was huge, had separate tub and shower, and the veranda was very, very nice. Overall, the ship was clean, well-run and a pleasure to cruise on.
Of course, we also ate a lot last week. We had dinner in the main dining room everyone night except one. We sat at table 132, right at the stern with a great view out the large windows. The food was very good, and what I expected. Not five-star, but no complaints. I actually thought they did the best with deserts and soups (soups were five-star to me!). The service at times was a little slow, but everyone who worked out table was extremely nice and eager to please. Karin, the assistant dining room manager, is in a class by herself. She made sure everything was in order, and took care of any concerns right away.
We tried the Pinnacle one night, and it lived up to expectations. All the food was fantastic, and a cut about the Vista dining room. Worth the extra $20 for the food and experience.
