It sounds like the "lucky" cruise ship patrons only come down with projectile vomiting and diarrhea due to norovirus. The unlucky ones end up on some floating disaster like this. It sounds to me like it'd be more fun to take a "cruise canoe" through a mosquito, crocodile and snake infested swamp. At least that would be a more fun survival scenario. Trapped on a floating barge in the middle of the ocean with a bunch of people dressed to the hilt sitting at dinner tables whining about the delay of their expected lobster dinners would be a nightmare.
