My wife and I will be sailing on the Oosterdam in November. I understand that 24 hour room service is available. Is it possible to order a complete dinner in our cabin or does the room-service menu just include sandwiches and such?
Yes, you can order a complete dinner in your cabin but you can only do it in the evening - I think it might be 1/2 hour before dinner begins in the dining room, but I am not sure. There is a leather binder in the cabins which states the hours for ordering the complete dinner in the evening. There is also a room service menu in this binder.
Unless you have an SS or S cabin, the rooms are quite small to be able to sit down and eat a full dinner, other than just a sandwich.
Why not try the Lido for dinner some night when you don't want to go to the dining room. Check your daily program for the hours they are open. The entree is served to you, but the appetizers, soup, salad, dessert are buffet style.
