According to the new member guidebook, page 37, holding account points can also be used for the Disney Collection, Conceirge Collection, Adventure Collection, World Passport Collection unless the reservation is made within the last 60 days of your use year. You said they have to be used before July 03, so it doesn't sound like you are in the last 60 days of your use year. I don't understand either why you cannot change your reservation from OKW to a Disney Resort if there is availability at a Disney Resort. I would call back and ask for a supervisor.
