OK lets work through this.

if a park opens at 9 and you have an ADR before this then you will be let into the park before opening. 20 minutes before is a fair idea although people have got in earlier.

There will be a separate gate for ADR entry - they have a list of reservations.

Once in the park you will not be able to go to the rides and in any event it would not do you any good as they won't open until 9am i.e after you will already be having your breakfast.

Theoretically the earliest ADR's would get you the opportunity to eat and still beat the queues for the rides especially in MK.
