The reason it is never listed on the online entertainment schedule is it is officially "By Invitation Only" and this year is no exception to that rule, officially, if you don't get a seat (through luck of the draw on the AP contest or other special invitation), then you can't see it. That being said, there is usually standing room to the sides that anyone can use and often there arre standby lines, so it will usually be listed on the in park schedules that are printed.
