Didn't attend but I can't help but wonder whether if there might be another reason they'd rent a big hall and have several congos attend. If they use the local KH, it's free, right? But if they use a worldly facility, they have to pay. So could this be another way to make money by soliciting funds? You know, "Brothers, we have to pay for this facility. I costs $5000 to rent. Put your contributions in the box as you leave."
I wouldn't be surprised if this idea came from HQ as a new way to make some more $$. They're ALWAYS doing that now...
