It was not a good experience for a cruise trip. Oosterdam is a very old ship. It even lost all power more than 1 hour during our trip. Besides, I requested a 3-people balcony room but there was no sofa bed in my room. They asked me to sleep to the other room which was very far away from my room and it was so inconvenient. The good thing was that they finally asked somebody else to switch the room with us 4 days later. I was also charged some fees which were not belong to me, however, when I went to the guest service, the staff told me "it's impossible!" I insisted and asked for others help then they said they would investigate it. My friends in the same ship had bad experience too. Their sofa bed was broken and laundry service lost their clothes. I commented on a "let us know" card and expected some higher level person to meet us in person for some explanation or comfort words, but nothing happened. Most staff were very polite but the management seems to have problem.
