We are a family of 5, with a 16 and 14 year old daughters and 5 year old son. My wife and I are seasoned cruisers, including P&O, Princess, RCI, Carnival and Cunard.
Cruise departed Sydney, Port Arthur, Hobart, overnight Melbourne and Sydney return. This cruised suited us for the dates and ship rather than the ports visited.
Embarkation went very quickly, we would have been on the ship within half an hour. Even though we were Platinum members, we didn't really get on any quicker than anyone else as we had no real major queues.
