DoubleTree Port Huron
As Diamond, offered full breakfast in restaurant Freighters.
Can order either the full breakfast buffet (including cooked to order eggs!) or one of any breakfast item from the menu. When I chose pancakes off the menu, was told by staff "if you want to get some more fruit from the buffet, I'll look the other way".
Buffet includes breads, fruits, yogurt, oatmeal, grits, scrambled eggs, an omelet-like dish, french toast/waffles, sausage links, and bacon.
