Bro, if based on your calculations, then chance of getting a haunted cabin is indeed very high :x
Just for record, I stayed overnight at LW cabin many times, no strange sound or encounters.
Honestly, I only sleep half awake, I more worried in case the ship hit something and sink, ship too old and I have no confidence on the life boats.
The life boats long time no use, dont know if still works :x
Actually they conduct drill quite often. Saw that a number of times. But must also bring touch light in your pockets. Once blackout, even in the day, you can't your hand.
