Update
Ferry crossing was pretty rough but luckilly we had a cabin... definitely worth the £100 for our own space.
On into Spain and the campsite was good but the weather was wet. For about £15 a night we had a nice pitch with good amenities.
Biarritz has no campsites but the hotels are nice and not too expensive. Around £50 got us a nice room right in the centre of town and the surf was huge.
Heading south to the pyrennees with so,e spectacular roads and scenery with loads of motorbikes.
Now in south of France at Cap D Agde more to follow ... if we find an internet cafe!
