August Closure dates for haunted mansion?

[Raya]

Is there any way to predict when the haunted mansion will close to put the NBC overlay in place? We are considering a trip to the D23 expo, so August 23–25, 2019, with a few days at DL before/after. However we'd consider a trip without the haunted mansion a waste, especially in its 50th birthday year.

It starts August 20 this year, so it wouldn't be out of line to expect it to be August 19 next year.
