Since you used a TP hotel cert, once you checked-in, your cert was "used". There is no partial refund for unused nights and there probably isn't a way for them to easily "switch" to a paid stay once you have checked-in. And I'd guess Marriott will only provide them reimbursement for the nights you actually stayed at the hotel. So basically you are asking the hotel to "purchase" points from Marriott to give to you for nights they will not have any revenue from the cert or you. That is asking a lot from a hotel given the hurricane wasn't caused by them or their fault.

The hotel may waive any change fees because you checked-out early due to the hurricane, but I don't see them giving out points for unused nights. But hey, it can't hurt to ask them if they will.
