Indeed, that's the whole point of blockouts. Keep discounted annual members away from days that are projected to be crowded with visitors. The opening of Star Wars will be hella crowded. If you need to see it day one... buy a one day ticket, upgrade your pass or wait.
As long as they are honest upfront at purchase about the validity of the pass.
There really is a strong entitlement that people feel they are owed first crack and also owed the cheapest access.
I honestly don't think this is an attempt of Disney to 'screw' pass holders. They just can't afford to have a sizeable portion of 1 million pass-holders show up eager to be 'first'. Disney is just softly forcing a portion of the 1 million to wait a couple weeks.
Despite my excitement - there's no way I'll attempt the first few months.
