Cold Breakfast was included in our Mousesavers rate. There was also a Hot Breakfast you could pay for that was equally good with a cook to order chef, but we stayed with the included one. You are seated and they bring your drinks. We had Melons, Pineapple, Strawberries, Grapes, Bananas, Oranges, Yogurts and variety of toppings like granola, nuts, raisins, a few cold cereals, toast, several muffins, croissants, bagels, donuts, pastries, and variety of spreads. May have been more but that is what I remember.
No early entry, yes to parking fee at the parks, not sure how room numbers work...would just ask for fireworks (or front of resort) view.
