I think cremation is probably easiest. The whole buried without being embalmed has to happen pretty quick to be viable, which means it probably needs to be arranged in advance. Years ago I looked into it. In VA, you need special permission to bury a body on private property, but not cremains.
I would say keep in mind who's going to actually be dealing with your dead self.
Dad made an off statement when he got cancer about being buried with the dogs and apparently never thought about it again. I looked up what needed to be done, should I have to bury him. Figured out cremation was the way to go, given his wishes. He survived cancer so, obviously, the subject lay dormant.
It came up when he was hospitalized and he was surprised that I had it all worked out already. *shrug* It still hasn't actually happened, because I want to do it right, but that's the plan and he's in a trunk with his personal effects until then.
Anyway, point is, make sure the person dealing with your body knows what you want and is prepared to get it done according to your wishes.
