Here are my thoughts on the Main Event:
Prepare to be in line. :-D
* Line outside (in the night heat at least so it's a little less humid) to get into Queue Hall
* 6am, QH doors open
* Wristbands handed out to each area as you go into QH
* Line inside QH to go into rest of convention hall
* 10am, general doors open
* Get into line in front of area you got a wristband for i.e. 'Celebration Stage'
* whenever that area opens, go inside - seating is requested to be done by 10:45am.
* after the event, sleep some more or power on to the next exciting experience!
If you are able to sleep anywhere (even in line), then best time is while waiting to go into the general hall after getting a wristband. You'll be inside in the A/C at least.
The only thing I would suggest about line etiquette is that if you are by yourself, just make friends with the people before you and behind you. Then if you need to leave the line for anything longer then a bathroom/food break, you can at least let them know you will be back for sure.
I'll probably plan to be over there by 12am'ish myself.
