Mountain dreams

New to the forum as hubby & I are earlyish in our plans with our grand move to France. We are looking at the possibility of running a small glamping & gite business and from what I've read it's quite difficult to get permission to open a new a campsite. I've also read that if any food is sold a gite business must register as a B&B. I wonder if anyone knows whether a small number of static, high end tents (yurts or safari), where meals are available, would actually qualify as a campsite or whether it could be classified as a B&B, and if so, is it easier to get this registered than a campsite?
