The nice thing about the Oosterdam is the layout is exactly like the Zuiderdam which makes getting about the ship easy. The decor is elegant.
Service on the ship was good for the most part. Our cabin steward was efficient and not to be seen, just the way I like it.
Unfortunately our waiter in the main dining room spoiled our trip the fifth night into the cruise. I was never able to find out why he was so hostile as he would not speak to me about the problem. When I complained to the dining room manager, I got a very cold response without the slightest apology.
