We thoroughly enjoyed this, only our second, cruise. We were particularly lucky in that our dining arrangements, in the Grampian Restaurant, were with two other couples with whom we got on extremely well. We had really great fun at mealtimes in the evening, helped no doubt by the fact that the table was hosted by an officer on each of the formal nights.
The cabin was adequate. Because we had such good weather, we were able to spend most of the daylight sailing time on deck. It would not have been so good if we had wanted to spend lots of time in the cabin. I had originally wanted to go for a Marquee Deck cabin (which would have given a bigger balcony) but they did not look much better inside and the balcony can be overlooked from Deck 9.
The embarcation process was relatively fast and efficient. So we did not need to wait too long in the relatively uncomfortable departure facilities at Dover.
Cabin 7023 is adequate for a cruise in which the weather is good and most of your time can be spent on deck. The balcony is not large enough to accommodate loungers (it has two chairs and a table) and is significantly overhung by the edge of Deck 8 but if you prefer shade it is fine. If you get a visit from the ship's cat you won't be able to swing it in the shower! And the safe is very small. For example it would not take a jewellery box. The indoor seating is not comfortable for any period consisting of a curved fixed bench type seat.
