Better view or your pin:
This is what usually happens at artist signings.
People line up, they get wrist bands, and then they open the doors for people to buy pins.
Here is what will happen that day:
Wristbands will be distributed entitling bearers to the opportunity to purchase limited edition pins released in association with the product release and signing. Guests wishing to obtain a wristband to purchase the "limited-edition" pins, will not be permitted to wait in line prior to 6:00 a.m. Wristbands for pins will be distributed near the East Entrance to World of Disney® Store (next to La Brea Bakery) one hour prior to park opening until one hour past the opening of Disneyland® park. Wristbands will then be available at the location until 12 Noon or while supplies last. In addition, holding a place in line for others in your party will not be allowed. Guests who wish to obtain a wristband to purchase a pin must be present when the line forms or they will be escorted to the back of the line.
Wristbands will be valid for the purchase of the pins at the designated merchandise location until 1:00 P.M. on the day of distribution. Wristbands are limited. At 1:00 P.M. any remaining pins will be available for purchase at the designated merchandise location by persons who have not previously purchased the pin(s) on the day of release. Lost, stolen or damaged wristbands will not be replaced. Wristbands have no cash value. Restrictions apply. Subject to change without notice.
I suggest you get in line and get the pin. It has been from my experience in the past that these pins do sell out and they are hard to find.
