I believe that the luggage is always off loaded by crane in LAX. Just the way it is done at that terminal. Probably the ship being late and if the crane driver was not there that made the situation chaotic.
Linda was on the Voyager in LAX and is currently on the Mariner. She said the decor of Prime 7, Signatures, Compass Rose, La Verandah and the changes on the pool deck are all the same. So they may have been consistent in this refurbishment for both ships.
