I agree, October 31 is Halloween. However, my birthday is on (a date) and I often celebrate it on the weekend nearest. I view the moving ToT the same way.
The worst excuse to move ToT was the one my hometown used to use- the big high school football rivalry game (and the last game of the season) was always the Friday around Halloween. If the game and Halloween fell on the same day, guess which got moved? 
That would work if the suggestion were only to move it to a weekend, but there are suggestions here to move it several weeks so that kids affected by the Hurricane can t-o-t. I see that as beyond the pale.
I'm just suggesting wait until things return to a semblance of normal. Streetlights working, streets clear, homes have power.
that could be weeks or even months in some areas. Life moves on. Moving it a day or two, I'd said is marginally ok, moving it weeks into the future,,,not so much, Months? forget it. When we had the October surprise here, I had friends with out power for 6 weeks afterward, and that was not nearly as devastating as this is....so let's give a 4-6 week conservative estimate, people are supposed to hold T-O-Ting in December because the kids missed out? I really think that's more than a bit much. 4 weeks would put it at thanksgiving weekend. From personal experience, in something of this magnitude, even if power is on and streets clear the adults in this situation will be eyebrow deep in dealing with FEMA and other aid agencies for ages. It can take weeks to get help where it's needed. For the most devastated areas, people may just be getting out of temporary shelters over the course of the next few weeks.
So this year the kids will have to do with out.
