The only restaurant that fits those requests is BOG at MK. That is the only QS credit breakfast that takes ADRs. Because that’s the only pre-park opening breakfast that gets you past the castle, it tends to be a difficult ADR to get.
You could try setting a reservation finder, many of us have had good luck getting an ADR with that. Also try booking ADRs for smaller groups within your party (for example if your party is 4 people, book 2 ADRs for 2 people each at times that are close together).
