No. Cash nights through the regular Disney reservations office come from a different inventory.
Those cash rooms come for several sources.
1) Unsold points. Any point that Disney owns through either not having sold them in the first place or reacquired through ROFR translate into rooms available for cash.
2) Members trading to non-
DVC locations, like
Disneyland hotel, Adventures by Disney and cruises in effect turn rooms over to cash to offset the cost of the trade.
3) Any DVC inventory rooms not reserved on points 60 days out become available to cash. These rooms, if not already rented, can be reclaimed for point usage...but this is also the least likely source for cash rooms. AKA "Breakage Inventory," some of the income offsets dues under the "breakage income" line item in the budget.
4) Retained inventory. Disney/DVC retains an ownership interest to use for rehab and repair. If rooms are not needed for rehab/repair that can be turned over to cash.
