We sailed the Noordam on the Millenium New Year's cruise for 14 days. The food and service were excellent, but our cabin( a standard outside) was awful. The air conditioning never worked properly, and the bathroom plumbing was not functioning most of the time. The cabin temperature was so warm that I had to leave the cabin the minute I was dressed for dinner, or I would have been soaked with perspiration. I waited for my husband in one of the public lounges, or he waited for me.
I suggest that you test your air conditioning and plumbing upon boarding, and if it's not satisfactory, go to the front desk and have your cabin changed immediately. We did this too late, as many people seemed to have the same problem and they no longer had any cabins available. We would have taken an inside cabin, but they were occupied as well.
We have not sailed Holland America since, as we feel they should not have charged us this much money for a ship that's getting long in the tooth.
