Like you, I would be fuming - really annoying to go to such lengths and still end up disturbed.

But, whilst you can reserve a Rewards room for a third party, elite benefits attach only to the room you occupy. I did this recently for my wife and daughter redeeming my points at the Times Sq Ren. The property very kindly afforded my wife all my elite benefits which she wasn't expecting as I'd told her all she was likely to get was the basic room I'd reserved. It was totally unexpected because she wasn't entitled to the benefit. Like my wife, you cannot expect your elite 4pm checkout benefit for your friend even though you arranged it carefully it still attaches to you and only you.

If I'd been sleeping in the room I'd be chasing for 20,000 points - a full rebate of my utterly pointless night (I could have gone home driving an extra hour and did this for undisturbed sleep) and the same again to enable me to enjoy that peaceful night they still owe me. I'm not sure where your 50,000 comes from.
