We have stayed on deck 3- dont quite know what you want to know so will just post as I found it. Had an inside cabin- fine, functional- midship, near lifts. Was quiet and easy access up to Decks 5 and 6 via lifts or stairs. If the motion of the ship is what you are concerned about- not much motion felt at all, even when sea was choppy. No noise from above or below or the engines. All in all a good deck. Hope this helps- any more specific questions, just ask.
That was very helpful, we have booked for next year, never cruised before and we have paid extra to choose our cabin we are on deck 3 cabin 474 i think, are the cabins ok, read a few reviews saying they were old and tired. thanks.
