There is nothing wrong with The Members of Your Chapter doing what they are doing. Time away to have some fun is not illegal. It just helps to rejuvinate a bit. A Conference that is required is not the way to do it.
What seems to be wrong is Your HQ and their Requirements.
There must be a change, or, they will have less Chapters and even less Memebers.
I am in no way degrading Your Organization, but it does seem to be a bit over the top!
