Sounds like a reasonable assumption. It seems to me the more "rustic" the housing is, the more likely people will be to only leave footprints. If there's no electricity and flushing a toilet is dumping some sawdust over your exctrata, people are probably more likely to take their trash out with them.

I think in the short term tiny house rental there could be very clear advertising and instructions that would probably dissuade non-compliant folks from showing up at all.
