Only the resorts included in The Disney Collection (so I think that's mods and deluxe that don't have
DVC). And you couldn't apply.anything to what you already booked. They are two totally different systems and companies. You would have to cancel what you have and book what you want with points through DVC Member Services. There is also a $95 charge for doing this, it's considered going outside DVC. Generally it's a pretty poor use of points, economics-wise.
