Okay
For any of the AP Previews way more AP holders DO NOT get a time compared to those that do. It is not feasible to spend that many days in previews. In this instance they may have considered how many guests already have MK Park Reservations and determined it made no sense to open it up with so few reservation slots left. The VQ system works, it will work well for this. There will always be guests not happy about the process or results. You just can't make everyone happy.
NOTE: Undesirables are
Disneyland locals ... not WDW. And I would guess more Orlando locals are Universal and SeaWorld AP holders than are WDW AP holders ... therefore they don't impact WDW like the locals at Disneyland do.
