Reward Certificates are void and will not be honored if bartered or sold for cash or other consideration.

So as others have said, it is both tacky and a violation of Marriott policy.

Marriott is happy to allow you to give away you certificate, but they are the only ones who get to charge for the rooms.

pd I have always pay my travel expense from my own dime. When I was doing well I gave for free some miles to a friend that was going through a difficult period. Now I am also going through a difficult situation and although I still have a bunch of points/miles, I do not know if I would give it away so happily.

Wow. That got personal quickly.

If you're staying in the room with him and you're using points because it's a better value to use points than pay cash(which I've seen quite often) then I wouldn't charge the value of the points or best available rate because I think that's really higher than fair market value.

I would go hit up hotwire and look at their price for something in the category of hotel you are staying in and charge half of that since you're splitting. So that they can't argue that you're ripping them off because that would a reasonable alternative (when Best Available Rate probably isn't)

I think of points as currency and sometimes it's a good value to use it and sometimes you should just pay cash. So, I can absolutely understand charging him. Another option is doing cash + points and making them pay the cash portion.
