My wife and I generally choose a cruise because of the ports visited and not the ship, however we did find the Noordam was a poor choice compared to other ships we have been on. Our verandah stateroom, 4016, was poorly positioned, jutting out from the decks above, resulting in coffee spills,wine spills, cigarette ash, etc from above. At times the verandah was unusable because of smokers above and alongside, (many cruise ships do not allow smoking in staterooms or on verandahs).
The stateroom also had problems with the toilet, bath, verandah door, (wind noise).
There was no coin operated laundry, which does not help on a 22 day cruise.
One major control error was that signatures were never required for on board purchases - in a few cases we were double charged and could not prove they were not ours - to Noordam's credit, they did credit us, but we wonder what would have happened if they refused, or our ship's card was used wrongly!
The food was adequate without being great, however the staff in the Vista Dining room were dysfunctional, and often got orders mixed up. On many nights we were more than halfway through our meal before a wine steward turned up.
On the credit side, arrival/departure/embarking/disembarking was excellent, as were the shore excursion organisation.
