There's countless methods.

Contaminate the food, Infest the rooms with bugs/Insects by bringing them In yourself, open the heating/air conditioning and pull out some wiring, block the toilet and sink and the list goes on.

Then hit your complaints.

Just brainstorming...

I think an idea would be bad door security and someone stole your phone.

That way you dont need to take pictures.
