Camp NaNoWriMo

Back in November 2011, I successfully participated in National Novel Writing Month (NaNoWriMo), and since I've recently been getting back into the writing vibe again (meaning that I've finally overcome the fiction writers block that followed on from last November's crazy 50,000 word marathon), I thought that this was an excellent time to take part in Camp NaNoWriMo.
The novel that I'm intending to work on for this new challenge is actually one that I've already started (cheating I know), but to be fair, I've only written the Prologue so far, and that doesn't count....right??
Typically, when I did NaNoWriMo last November, I didn't get off to a great start, because I had my birthday weekend right at the beginning of the month, so I quickly go behind on the writing and only at the very last minute (almost literally) did I manage to catch up with myself. For Camp NaNoWriMo, I'm going to be away for a large portion of the second week, as well as the following weekend, which is at least seven days when I'm not going to be able to write to full capacity. Five of those days, I will have the laptop, but I probably won't be able to reach a high target. So, yeah, as you can imagine this is going to be a good challenge.
But, even though I remember last November being incredibly stressful at times, at least it got me writing and my novel managed to progress much further than I could have imagined, so I have strong hopes for this one.
The only difference this time is that I'm not going to be doing it for charity. I think that I'll save the charity ones for the November challenge.
I'm starting to ponder how much preparation I should do for this novel, because I did quite a lot for last November, and to be perfectly blunt, most of it just confused me, and I ended up ignoring it, because I think that sometimes it's good to have a more rough idea of where something is going, and from there just to allow things to flow naturally. If it doesn't work, well that can be changed at a later date. It's better to get something down, than to just stop because of limitations caused by a die-hard plan.
Is anyone else planning on taking part in Camp NaNoWriMo through the month of June?
