We have done two long weekends this year (Whitsun and July) plus two weeks in France (August) but am just wondering if we can squeeze in one last jaunt... however, the next weekend we have free is the start of October. We have never camped post-August with the kids so kind of forgotten what it's like that time of year, is it normally bitterly cold at night? (We would only go if the daytime weather was reasonable, ie dry!)
