not enough info, what 3 nights ? Mid week you have zero shot... weekend either end, chances are better, they hold inventory for cash and non members as all
DVC's do, about a month out you can get lucky if you are willing to go on those high point fri sat and either sunday or thursday... two bedrooms do seem easier, but I hav had studios be easy too. I think if you sayanything, and they let go of the cash rooms, you get the two bedroom for the obvious reason...
