We are planning to go over to France end of Sept and spend about a month, travelling down into Italy. I have some guide books etc and will check websites in advance to see what the places are like, but I want to be versatile depending on weather etc. Camping in the past we have always found somewhere even in peak season, but am I asking for trouble with a caravan if I just turn up? My experience with both campsites and hotels is not to leave it too late in the day to start looking for somewhere.
