For example, if
DVC adds more on-site properties to the mix, that could make BCV rooms harder to get. However, if they restrict our flexibility in the system, that could open up some availability at all resorts. Until DVC implemented the "one transfer" rule, availability at the smaller resorts was very limited. For now, availability seems to have opened up a bit. However, adding other resorts could really skew that again.
Good luck!!
