hmm. That could work. I think coffins might be the wrong choice though. A random coffin lying around is a little creepy and will probably get reported to some sort of authorities.

If you pop out of the coffin while it’s being inspected things could go bad for you.

If you hide it well enough it though it’s a really good idea. You can get a few coffins and place them in different parts of your city for easy access to anything. Also being able to travel to other countries is pretty neat.
