In true Watchtower Cult behaviour the family can't just discuss their preparation for the convention in a normal manner, they make a family worship night of it. This elevates the arrangements to beyond practicalities and glorifying the GB and their provisions. This is also enhanced by their crazy ideas that these are theocratic arrangements.
It's so funny that they encourage the sheepies to do a dry run, what an honor this must be to be involved in a pilgramage. This is made even more special by the personal appearance of GB members whom they put on a pedestal by advertising that they will be there and telecasted from that location to many others. Yep, they get to see them live, in concert, all for the cost of a mantra ticket - bargain, the City of Atlanta thank them sincerely.
Regarding the scripture of Revelation 7:9 that they discuss, who needs Armageddon when they themselves have already identified who the great crowd of Revelation is? Talk about running ahead of Jehovah. That was supposed to be a future event. I just don't understand why they haven't instructed them to wear white robes.
