WVL and BCV are resorts. By celebrate, do you mean send a card/balloons to the room? If so, they don't discriminate by cash or points rooms.
Having said that, just because you tell them about the birthday, doesn't mean they will definately do something. Each time we informed the resort check in desk, we have been surprised with a card, balloons etc. but I have read of others that were disappointed when nothing appeared.
My advice is to call MS and have them add the birthday note to your ressie. Last time I was asked which day, and on that day a Magical Moments certificate arrived from someone at
DVC. I never told the resort about the birthday, so I know it was MS that sent the surprise along.
