Pretty much they have the park from EARLY Morning until around 11 AM, live remotes (News channels, such as local KTLA Channel 5 is broadcasting the Morning News from the park) and then the official opening at 10 AM. Signage throughout the resort are advising the entire Paradise Pier area will not open with the rest of the park, but around 11 AM. Once the Grand Opening ceremony is over, they will clean up and then allow guests to get into queues.
I presume they will start a queue somewhere near the Farm area for Toy Story Mania at 10 AM, and then "walk" the queue to the attraction when the area is clear, around 11 AM.
Tonight, The Paradise Pier area will be blocked off for a Media Party, basically Toy Story Mania!, the Midway Games and Pizza Omm Mow Mow.
