I think most people will prefer to be on their home server, and not hopping around for the final hour. And most already have plans for the final hours. Myself, I will be going to bed early and getting up at 2am specifically to be there for the final hour, so I would really hate to find myself locked out of Virtue, my home server. I'll be on the air for The Cape Radio from 1pm-5pm eastern, so I'll probably just leave One Hit Wonder parked and the game running until I get back, but if the servers crash and I can't log back in, I'll be rather upset.
If you want to do something earlier, that's great, but let people have the final hour to honor the game in their own fashion.
