Jane, we drive cross Europe every now and then all the way to the southern Spain but not with a camper but a normal small car. Our cat travels along as we can't leave her behind; besides she likes warm south. We don't drive fast, we stop for days to rest and paint pleinair in France, of course. That way everyone can have a good rest in between the driving days, especially the cat. We were suppose to drive this fall but something unexpected came up so next time we'll try in spring, in about 3 months. That's the plan, will see what happens.
I was following news about the bad weather and many deaths near Valencia, I'm not sure if Alicante was as bad as Valencia but Malaga area had some danger and some unfortunate deaths. I don't know how to avoid that rain when it decides to fall. How can you ever tell if it's normal heavy rain or something catastrophic?
Hope you get to go again and for a longer time period. 7 weeks sound short for sure. We will be next time 3 months.
