The bit at the top of the main car park is a little detached from the car park itself - it's a little grassy area with at least one table-bench; the village and public loos are just a few minuets' walk away down the footpath. The car park is now locked overnight so whoever does the locking would be on the lookout for cars still in the car park at shut out time (and any tents in the little grassy area). Guess it's not such a good idea to camp there after all if you're with family but it might be an option if you're desperate.
