Basic Q re FPs: Latest Time Possible?

So if MK closes 9pm, will I be able to make an 8:55pm FP reservation? Or is 8:45pm latest? 8:30? For example hoping I can do 6:45, 7:45, 8:45 on day we arrive…?

I think with the exception of Illuminations your last FPP needs to be at 8pm

The latest I recently was able to get for 8:00 closings was 7:30. The window is usually an hour but for my 7:30 one it is 7:30-8:00. I am hoping those hours will be extended but they have not for now.

I made an 8.30 for Epcot when it was closing at 9 but I don’t recall if anything later was available.
