I was looking at some old sail and sign cards, and, remember the days of innocence, when the cabin number was imprinted on it? The earliest I can find is my 96 Soverign cruise..cabin 8592! By 99, cabin number on this line was removed.
RCI use to give all passengers, a list with names and states..Maybe addresses too, but I mised out as the computer was broken on my 1st cruise, and then, they stopped the practice:(
How times have changed:(
