To start with the ship is not new.
It has had a refit before joining the Marella cruise line.
Tired, old, battered, broken but areas are clean, staff try really hard to make things look good.
Poor cabin, whole cabin tired, battered, refurbishment did not spend enough money on the cabins.
Broken air conditioning, toilet, no hot water in the shower, which was not fixed during a 2 week cruise
