@Way New,
I think you not only have thought on the situation a lot, but covered most of the bases.
I think the logistical aspect would be the bottle neck. Do you, or can you feed all those people? With the number of people within the HOA as well? There could be competition for resources.
Group dynamics. That is always an issue in any setting. Who leads? Who follows? All it takes is one to be a horses patoot and send the whole group into a tailspin.
Have you done a asset vs liability assessment for each person?
And when under stress, some will have a lower threshold to go into hysterics than others. How will you deal with that?
Granted some will rise to the occasion better than others. There may be some surprises. Those you thought would fold like tissue paper in a hurricane may step up. Others you thought would be a rock, fall into depression, curl up in a corner and rock back and forth while sucking their thumb.
