I actually feel a lot more comfortable "harshly using" (not really vandalizing, but making full use of) a hotel than someone's airbnb, couchsurfing, or friendly couchsurfing arrangement -- because it's an impersonal commercial space, I'll use all the water I want, leave wet towels all over, etc., whereas at airbnb I feel like I should be even more polite and neat than I would be in my own home.
Interesting point -- I wonder if people who enjoy breaking things are more likely to use AirBnB, since they're destroying something that really matters to someone.
