We sailed on the Zuiderdam (i.e. Sewerdam") on a 22 day cruise beginning April 14th 2015. It was our second Holland cruise (the first was uneventful, but I was not overly impressed). On the bright side... we had 22 days of excellent ports, and the weather was outstanding (sunny, 59 at night and low 70s in the day).
The ship should have never sailed. They had an Italian labor strike during the “refurbish” which left the ship half-baked at sailing. We were given keys to our SUITE (6098), and upon entering, the bathroom was locked. The steward said there was no water, but we later found that of the four sewage processing systems on the ship, number 4 was not working. It affected a large number of toilets on every level of the ship. We made new friends as we waited outside the limited public bathrooms that worked (many were affected by the outage). It was not as if we had a clean sparkling bathroom that did not flush, there was human waste in the commode. We were given a key to a room with toxic waste.
We were without toilet and water (as were MANY others for a full day, and then interment ant problems with the toilet. The electricity would flip a breaker multiple times a day/night and we would have no lights. They finally found the problem on day 3. Because of ongoing construction, half of the top deck was off limits, which made the stern Lido area VERY crowded. We would leave on an excursion and return not knowing if the toilet would work or if we had lights when we got back.
