You'd be insane to doss at the NF carpark, especially at busy times. Not only is there now a very real human waste issue (the whole carpark pongs at times), expect to be kept up half the night by other teams arriving, talking loudly, clanking their hexes, playing car radios, etc.
Plenty of other options, for example the nearby Nevis Range car-park is huge but generally empty. Wherever you do go, I'd urge you to bag or bottle up your your poo for later hygenic disposal.
