I was nervous about this 50 year old ship but we chose it for two reasons. The itinerary to the fjords and its ability to get into ports like Flam and the fact that it was small with only 800 passengers. Unfortunately it was 800 passengers crammed in giving far less square foot per person than the bigger ships offer.
Arrival at the port - this was chaos with a long queue to get to the terminal only to drop off our luggage and turn around to drive back over a mile to the actual Tilbury port and docks to park our car. Why they didn't direct people who had paid for parking to go straight there I don't know. The queue was over a mile long and we were 90 minutes late checking in, which was very smooth and painless like others have described.
Our cabin was 638 on Deck 9 and although quite a high category it was still very small indeed. Clean and bathroom was sufficient but it just felt a bit cramped. Only one power point (unless you unplug TV).
Our cabin was on deck 9 which was the promenade deck. This gave us easy access to the outside however a small amount or obstruction due to the lifeboats on the deck above.
