Sorry I didn't answer sooner, I somehow missed this thread!
Once when I was trying to add a studio to an existing reservation at the BWV but they were booked up, I booked one using cash as a backup. At various times I had different combinations of points rooms and cash rooms and every time both CRO and MS told me it wouldn't be a problem to link up the reservations.
Although this is not normally the case, this year there have been extraordinary AP discounts. You might want to call CRO (the regular normal reservations line) and see if you can get OKW on an AP discount for the nights you are looking for. You can also check out
www.mousesavers.com for other codes that are out there as well. After you have your reservation through CRO, call MS and see what you can do about linking them all up.
I just checked travelocity (which is showing one of these "coded" rates) and they have an OKW studio for $179, 1br for $244 and a 2br for $339. I know that the AP discounts (if they have them) are even better, $269 for a 2br (but remember to add 11% tax to those numbers).
This invenory is not out of the 60 day breakage point inventory but rather comes from people who have traded out their DVC points for cruises, II exchanges, concierge collection etc... so you can check right now for availability.
Hope that helps!
