The service staff can pick ships they wish to work upon just like we can pick ships to cruise on. The major difference being they pick a ship to work on for months while we pick a ship for a week or so.
Staff is always rotating between the ships. Every week, staff are arriving and departing.
Not entirely correct. The rotation of crew are based on the ship's needs of staff, so the crewmember itself is not really choosing. During the crewmembers contract he or she can be transferred to other ships.
It's correct that every week has a certain number of sign ons and offs.
