That's not
quite true. Owners are allowed two guest certificates per year during blockout periods. Still hard (you need to find someone who still has at least one of their exceptions left) but not impossible.
(There is also an exception for owners traveling with their guests, but that's probably even less likely to apply here.)
Of the other Wyndham Orlando resorts: Cypress Palms and Reunion are also blocked out then, but Orlando International and Star Island are not. You can see the full list of resorts and blockout dates here (no login required):
