I don't know if it's available anymore.
It used to be a free option for people staying in the Disney on site hotels which allowed you to take your breakfast in the park one day and ride the fantasyland rides early (this was back before EMH existed).
EMH means that now, there's very little point to this. A much better idea is to come straight in for EMH, then leave and go back to your hotel for breakfast after - you'll get more done than if you did a GMF breakfast as you'd lose valuable time eating then while everybody else is riding and exploiting the empty queues.
