Oosterdam is beginning to show its age, but neither more nor less than any other ship from the early 2000's with only a single refurbishment.
Cuisine choices are good to excellent, though the open seating option seems to present problems for both the kitchen and the waitstaff. The Canaletto option is inexpensive but good, while the Pinnacle can be either very good or superb.
The hotel is once again under the direction of Mr. Deering, with whom we sailed on the same itinerary back in 2005. Our only problem was a somewhat chaotic debarkation owing to delays presented by Customs and Immigration.
Typically a bit shabby for its age, but not oppressive for a window cabin. Very quiet with the AC providing white noise to conceal all the hallway bumps in the night. For economy book an obstructed view cabin, which isn't all that bad when you consider it saves up to $200 among the other windowed cabins. Verandahs can often be had for about the same price close to sailing dates.
