Some French say that they don't feel this comfortable in Dutch-owned campings and the ones where you're the majority of the clientele.
Because most Dutch wouldn't make an effort to speak French. Some camping's websites are poorly written in French. And, as you may know, the average French has a poor command of English. All this limits interaction. It's not a very big issue for small children, who manage to play together in spite of language barriers. But for teens and young adults, for example, it can be boring not having people to spend time with.
A ghettoization follows. French aware of this avoid Dutch campings, which is the case of a friend of mine (besides age gap and expensive prices). For example, in the Midi-Pyrénnées region (Southwestern France), there are 9 "French" resorts and 6 "Dutch."
So, as I said, I ignore what Dutch would think about all this situation.
Moreover, it makes me think about other stuff. The development of naturist beach and sun tourism in France and Spain is in part indebted to German tourists (more info
here), whose free body culture sparked important developments in capitalist naturism in those countries.
The Dutch model, where you set up campings for Dutch, prevents you from exerting a German-like influence outside your country, as you don't stir together this much with nationals.
Of course, I don't know everything about this, hein
Only preliminary thoughts.
