Disembarkation day!
I actually had a dream last night that while on the ship, there was this outbreak of a new strain of disease that had never been seen before. It was acting quickly, killing passengers within 5 hours of contraction, and no port would let us dock because we would spread the new strain. We were forced to float around aimlessly while we all died off from this disease.
Quite Camus-esque.
Possible NaNo.
