I really think you'll be fine. I think this is directly related to not enough reservations over the holidays the next 6 weeks for APs. Some dates are already unavailable. Adding more to the pool is likely only to upset people.
The fact they are still selling Pixie Dust AP leans to this ... these APs are mostly blocked out the rest of the year so they don't have to worry about the reservations.
BUT if they beginning selling again, I'd buy a voucher ASAP. Summer months and new rides opening could increase sales.
