When did you try to book? I would imagine that most
DVC owners who really wanted this night would have tried to book NYE by the end of February. Those who wished to change resort would have been ready to do so on 31st May.
I would assume that it wasn't just possible but very probable that all rooms for a very popular time of year would be gone nearly 4 weeks after it opened for everyone to book! I wish you luck getting your waitlist, but I don't think it takes luck to book it.
