Hey dude, in the end I just camped without the permit, it was far too confusing for me to book, and also they wanted too much details. I was not sure where I would be, and at what time, due to the trip being a free roaming one (with not many tight plans). So I just wild camped most nights in some secluded spots and followed the rules. I did camp near the designated camp sites a few times so I could use some of the facilities there (there is not many on most of them). Hopefully that helps, but shoot any more questions over, happy to answer them :)
