If memory serves, this is how the first MK After Hours events were. We went to one of the very first ones offered (in April 2016) and at that time, they were giving away tickets to DVC and AP members, media entities, sometimes just random hotel guests. All the talk on the forums was that this event was going to be a bust because it was too expensive for what you got and Disney was not doing an adequate job of advertising the availability. And now look at it! So I won't be surprised if the same thing happens with the AK and HS events.
However, I definitely agree that there are a lot fewer attractions open at AK which significantly devalues the event in comparison to MK for me.
