As usual it is scheduled at a non family friendly time. I guess it will be many years before I get to attend one.
I can not speak for other clubs, but there is no way that we would have been able to get affordable rates for hotel rooms prior to Labor Day. San Diego isn't called America's Finest City for nothing. Until MACNA attendees are willing to spend $200 - $250 a night for hotel rooms, figure it will always be around Labor Day weekend.
