There are quite literally many thousands of guests who have been allowed to enter the (still closed) park well before the posted opening time, all being held in the central areas of DHS (in front of the Chinese Theater, and near the Streetcar (Starbucks) Coffee Shop on Sunset Blvd.) all waiting, in many cases multiple guests "deep," at all of the portals that face the entrances to Star Wars Land, Toy Story Land, and ToT/R'n'RC.
Once straight-up "opening time" is reached, they are all released at once... and many (MANY) of these thousands will walk very quickly (Yes, some will attempt to run) toward the various opened attraction areas.
Quite beyond anything I've seen at WDW since the place was first built.
It is scary.
