CRT Breakfast - When to arrive?

I have an 8:10am reservation for CRT breakfast. What time should I plan to arrive at MK entrance to make the most of the opportunity? I’ve heard we should get there early for pictures?

Magic Kingdom has a new opening routine. I would be there at 7:45 when they begin to let everyone in to Main Street.

They will let you in at 7:45, we just did this on Sunday except we ate at BOG not CRT. I would be through bag check and the tapstiles by 7:30.
