You can get in the park at 7pm. Not as good as
MNSSHP or
MVMCP, but at least you get a little extra time where you can take advantage of rides, dining, whatever you’d like.
The park closes for all DAK DAH dates at 8pm, event hours are 8:30-11:30pm. That ‘extra’ 30 minutes is bonus time, to some extent, for DAH ticket holders. It’s also convenient in that’s 30 minutes for day guests to clear out and ride lines like FoP and NRJ to go down so you have ‘better conditions’ at the start of the event (if that makes sense).
I have not attended DAK DAK yet, but I’m a fan of the DAH concept in general. We’ve done MK and DHS and thought it was well worth it.
