With MGM hotels, there's no margin for the hotel to do anything with points stays. Just book the room you need or ask the front desk about upgrades at check-in.
FWIW, Points & Cash is always a bad deal - either you should spend all points (buying points during the 25% off sale if necessary) or all cash.
