Here is the official Briarwood scoop regarding the iPad Release on 3/11/2011:
Customers wishing to line up in the early morning hours for the iPad 2 release should do so at Door 4 (between J.C. Penneys & Macys). This is where the line will form. The entrance doors will open between 7:30 AM and 8:00 AM. Security will escort customers to the Apple Store. Anyone in front of the store prior to this will be asked to leave the mall.
The handicap doors will not be unlocked early. This has been done in the past for those attending training sessions at Apple. If you are attending a training class, you should not get in line for an iPad. The customers for the training class can come in and then the doors will be re-locked.
That's it. Briarwood will allow customers to line up early in an orderly fashion.
