Well, it's a 13 night cruise, if someone dies, like your parents, siblings, kids, grand kids, I would like to know. At the beginning of this route, you might have a chance to disembark, fly home, attend the funeral and support the people left behind. Otherwise they are buried, and ceremonies are held before you get home.
If there is a case of bad weather, a flood, a fire and your house is destroyed... yeah, not much you can do about that, and if you would go back you have to go to a hotel anyway. So, less need to go back immediately.
