Mobil-home with ac or camping with lot of shadows?

This last may I went to a camping in the Ardenne french side at Lac des vieilles forges. We rented a mobil-home (chalet) and it was with AC.

Now I'm searching another camping close to a lake/river and/or with a swimming pool that has chalets with AC and doesn't cost 200+ €/month.

I suffer a lot for the heat, I have panic attacks, and I'm worried last week of July/first of August is could be really cold. That's why I want AC.

For the moment I didn't find any.

If nothing, do you know a camping really full of trees in a forest area so that I can put my tent in a place with lor of shadows?

Thanks,
