only thing I did not get at 180 was CP pre opening; kept checking and snagged a 8:15am a couple of days later. Other than that only hoop de doo is elusive, but that is because its not loaded/may be down for refurbishment.
I kind of fondly remember my first trip with my brother, where we went with the flow - called the reservation line early in the day when we had decided where we'd likely be and just ask what they had around when we wanted to eat. Worked out nicely, but now I know too much about the restaurants and have made favourites, lol!
