You'll probably struggle to find space when you arrive on Friday, there are no allocated pitches it's a free for all
The smaller the space you require and the earlier you get there on Friday the better!!
Once you've pitched and you leave the site try to mark out your car space with barrier tape otherwise you'll come back and find someone has pitched a tent in it (tip try to avoid pitching your own tent in the middle of someone's camp or their car space it doesn't make you very popular...).
Getting to Carrefour this year on the Friday will be a nightmare - the roads are being dug up for the tram system. I would strongly suggest you go to one of the supermarkets in Arnage - see other threads for details!
Have fun - next year go earlier
FS - have you come out???
