No, you are paying cash and receiving an AP discount so you are not eligible for the DDP on that portion of your stay. CRO has a 3 night minimum on packages also.
So basically apply these rules for DDP:
DDP thru CRO=CRO package, 3 night min, no room discounts applicable
DDP thru
DVC=MS has to book, no minimum stay required, No ticket purchase required, must book using points or member discount cash.
