If you do, whether Hyatt or Marriott, you'd get the points/night credit & the credit card credit of 3pt/5pts. However, if TP Housing is paying for the room & you're paying TP Housing, then you will only get points for the credit card spend & not points for the stay or night credit for the stay.

BTW - what was TP Housing's quote for the Marriott? You said you contacted the Marriott directly. for the $600 quote.
