I appreciate the feedback. We will continue to gather feedback during and after this con and use it for decision making for next year. I understand what you mean about the separate runway vs skit. That is why we split them up before.
The problem is that we need to have our concert on Sat or Sun which leaves one of the cosplay events on Fri. For most of our history we have been Fri-Mon over Labor Day weekend. The problem is that the Friday before Labor Day is a school day and a large part of our attendance doesn't arrive until late Friday night. We've had complaints about this for years that members couldn't make the runway contest on Friday. This is what led us to the decision to merged them back to Sunday.
However, this is likely our last convention on Labor Day weekend. We are shifting to early to mid August to try to hold it before school starts. That will likely eliminate most of the concerns about having big events on weekdays, so it could mean we split it back out again.
We will continue to listen to feedback and try to make improvements.
