Getting an early, morning shot has become more difficult since they started letting everyone onto Main St.
A PPO breakfast ADR MIGHT work, but there are probably 100 other people doing the same thing, so it's still not going to be "clean," and you would have to do it very quickly.
Be AT THE GATES by 7:00 so you're at the very front of the line when they let you in and rush your family ahead of everyone else and you MIGHT get a clean shot.
A completely different option is to wait at the end of the day. Stay up at the hub and wait for the crowds to leave. This could take a while. The difficulty here will be how long the photographers stay around. I would start chatting with one to see how long they can stay or if they know who is the last one out.
