Do not ever plan to get some last minute task done at this show, like making a slideshow for your panel or finishing your mini-comic!
You just won’t do it!
Trust me on this. In the olden days I sat in the hall making Keynote presentations and ran to Kinkos to make flyers…no more. It is too chaotic and there are too many other fun things to do.
So, you have only 48 hours to finish everything.
There is one other hint and I mentioned it here before but I’ll do it again: poster tube.
