Renting out hotel rooms?

How bad or risky is it to offer a hotel room for a convention but not actually stay in it? I have a couple room reservations I want to offer but I have my own room elsewhere and I'm doing that so I can stack point bonuses (not actual cash profit) so my next convention hotel is free by using my points. I'll be there to inspect the room before and after but I'd be staying in another hotel.

AND you'll be responsible for any cleanup, theft, property damage or if they over stay. Just make sure it's people you know and trust.

Ah, so your plan is to rent out the rooms, accumulate points, and redeem a free stay. Yeahh, it's a bit of a high risk. Convention people are very messy and you'll be responsible if like drinks are spilled on the carpet or someone nicks the walls with makeup. Like ohnoes said, your friends would be fine cause they'd respect your position and be willing to help. Strangers will be a wild variable. Up to you.

Like others have said, people have a habit of trashing rooms and places that aren't theirs. If the room is under your name and not theirs, they'll have even less insensitive not to trash the place, and when they do you'd be responsible for repairs, cleaning costs, and paying for anything they steal. You might even get banned from the hotel.
