Sorry, am I understanding correctly that this means you can book a room ans then get the lower price if a discount comes out later? Does that happen automatically or only if you notice/ask?
We are also hoping to go in March and I was trying to rent dvc points, like the OP. I was pretty surprised that a lot of resorts they say normally book later had already filled all the DVC points-eligible rooms.
Needless to say, I want to get a reservation on the books soon rather than lose out on staying where we want to stay, so future Disney discounts being applied to already made reservations would simplify things!
