Reserving breakfast before the park opens?

Hello Disney peeps!

I reserved breakfast at CP an hour before MK opens.
How does this work, if it’s before rope drop?
Also how can I add it to the touring plans planner.
When I try to add early breakfast, it doesn’t allow it, because the planner sees park hours only.

Thank you!!

You should arrive at the front of a Magic Kingdom around7:30. You will check in all the way on the left (special line) and you will be let into the park around 7:45. They will give you a flyer to show the CM at the next check point. You will have a few minutes to take pictures on a near empty Main Street and Castle. Then, you will go to the next check in spot and allowed to go to CP. Enjoy!
