will depend how 'enthralled' I am by wow at the time, lately i've been going kinda hot and cold with it, lack of being able to heroic raid is dampening my enjoyment of it all. in the past i've been set to go with a few cans of relentless to get ahead of the pack asap, usually if you can get ideally a whole zone out of the way before the majority start playing you then get to either crack on super fast, or take it at your own pace from then on as you'll not be competing for mobs/spawns etc.
depends entirely when it is released, if I have any holiday time spare to take the day after off work etc. Next time I might just take it at my own pace, enjoy the story, take in the views etc...
If I want to go all out, I'll have a load of energy drinks, and a mixture of food stuffs ranging from sandwiches, pasta to finger nibbles etc and crack on from there. in that case I will get home from work, sleep through until 11 and log on then ready for the switch flipping at 12.
If I'm going to take it at my own pace I'll wait until the CE box turns up, install that, and just play an hour or two each night after work or something.
