There will be a line (it used to be on the far left) with signage for "Minnie and Friends Breakfast." You don't need EMH/early entry privileges. They will have your reservation on a list and you will have to have your park tickets ready in order to enter. We did this option a couple of years ago when our large extended family of 12 went for a day trip right after Christmas. It's a great way to extend your park day when you aren't staying at one of the on-site hotels or do not have a 3-day hopper.
