My advice would be to call and book the first night and then ask MS the question. They can usually tell by the volume of calls how quickly rooms are booking. If they say you'd be OK to call just one more time, I'd feel pretty good about waiting, especially if I am booking a preferred view.
That said, I'm an owner at BWV and we prefer the standard views. If I am booking a standard view, I always call day by day no matter what season or size of room. It may not be necessary, but I am not one who does well with "waitlist stress".
