From the victim's post: "...came into my home earlier this month (apparently with several others, according to witnesses)..." So there were several of them.

From the victim's post: "...came into my home earlier this month (apparently with several others, according to witnesses)..." So there were several of them. If this were a hotel industry conspiracy, I think it would be very difficult to pull off this way. All you need is for one renter to do this. Adding people to the conspiracy puts your conspiracy at risk of being found out. However, it's not too hard to imagine a random group of renters doing stupid stuff like this. Think about some immature people who weren't raised well and who are also drunk, on drugs, and/or slightly mentally ill. tl;dr It stretches the imagination less to chalk this up to a group of thugs than to a conspiracy.
