Cabin 5194Z sits in the midship part of the ship on deck 5. Midship means the central area of the ship. Deck 5 is close to dining, bars, and entertainment venues on decks 6 and 7.
The 'Z' in the cabin number means it is on the starboard side of the ship (right of the ship if you're looking straight forward). This can sometimes be important if you're doing a repositioning voyage like a Transatlantic crossing as it will determine if you will have the sunshine or not.
The Sea View cabins are ideal for sailors who want natural light and ocean views in a comfortable space. Most cabins include a large window and a built in nautical style seat, creating a relaxed spot to sit back and watch the sea throughout the voyage.
