They still start ressies at 8am. I would skip the breakfast during EMH. If you really want to go for an EMH morning, and you really want to try the Crystal Palace breakfast, try making the latest breakfast ADR possible (maybe around 11am or so?), arrive at the park 30 minutes before park opening, enjoy rides and attractions until your ADR, then you will still get to enjoy the Crystal Palace breakfast but it will be more of an early lunch for you, and you will probably want to eat by then anyway.
