Depends how you book the cash stay. If you book it through MS, it would be the same as though you were paying with points. Same housekeeping schedule and you would not have to change rooms or check out and back in again if you were combining the cash stay with a points stay.
If you book a cash stay through CRO or with the resort directly, you are treated the same as any other cash guest. Daily housekeeping, and if you combine the cash stay with a points stay, you may have to move/change rooms between the cash/points stay.
Best wishes-
