One more thing to keep in mind is fact that process of body decomposition is pretty fast, particularly in warm and wet climate, and process actually starts right after the death.

Without going into the details, important is to know that you need to have plan what to do with the body right away when death came, and some backup plan, and maybe one more backup plan.
For example you may be not able to go out and burn or bury the body for day or more.
