Like the Spirit, Sapphire was built as a dedicated cruise ship. The big advantage over Spirit and Ruby are the size of the cabins, At last a decent table and small sofa in all cabins except the smallest on deck 4.
Very pleasant watching the sea go by sitting in an armchair with a pot of tea and the sun just above the horizon.
On the Spirit and Ruby, the public rooms tended to be on the same deck which made for quick transfers between rooms except when side doors closed when show in progress. The Sapphire has public rooms and restaurants on separate decks which can cause congestion with the lifts. These need integrating so that one is going up as the other descends. As it was, they both tended to arrive at once.
5076. First cabin at base of Atrium. None of that cramped corridor feeling.Spacious with large windows. Large shower compartment but floor wrong in that water did not run away easily. After your shower, you were paddling.
There was a shelf beside the bed which could have a chest of drawers underneath as we felt more drawer space needed. The wardrobes were adequate. We like this cabin, so don't you book it when we want it!
