hi i'm a new member and wondered if anyone can help.i am in the process of finishing my self-build and hoping if all goes well to have short break away in it in august. the only problem is most sites want you to pre book and i'm a bit worried to book incase i can't finish the camper in time and don't want to waste money. doe' s anyone know of any sites you can just drive into without booking in around the devon and cornwall area.would be grateful for your advice.
