I don't think it a big deal. We have a Facility mandated rule to keep them parked till 1pm just for safety reason of cars driving around spectators. Traffic is tough in SoCal and people come from a distance. But I think you need to start awards around 2 pm and keep moving with a steady pace.
I've seen some other brand shows that did awards from 3 to 4:30 even. C'mon, get things going and stop with the gibber gabber!
