MK After Hours for June 28 - Park entry time?

I am doing the June 28 Magic Kingdom After Hours event, from 10pm-1am. Anyone have any idea what time I can actually get in the park? Without using my other days of course.

Also, does anyone know how to set up a TP for this event? I know I don’t need one as the lines are super short, I just want to keep track of rides I know will be open and what I need to ride before the event starts.

I believe entry begins at 7pm for this event.
