Any of the resorts have the basic breakfast plates, breakfast sandwiches and waffles etc. Sunshine Seasons in the Land at Epcot has the same as the resort CS places. Main Street Bakery has great French Toast loaf and the best ham egg and cheese croissants
That's the way we use the DDP also. On our two trips that included the DDP we stayed at POP and had breakfast at there. We had breakfast as soon as the food court opened so that we could get over to the parks at opening. We don't like to take away from our morning touring time in the parks by stopping to eat breakfast. If we are able to get free dining for our next trip we will do the same thing, most days.
