You cannot limit the number of visitors and let everyone have this sort of holidays.
The most beneficial way to limit the number of visitors for local communities is to increase prices.
If they want to reserve a number of places for people to be able to visit at a low(er) cost (e.g. through a lottery) then good for them, but there is no entitlement to go on holidays to others' countries or to unique places.
It seems like communities can be ruined by richer tourists in ways that not so rich tourists won't. For example, in Pembrokeshire and areas of Devon some communities have been partially replaced by clusters of second-homes because rich people like to have their holidays there. Locals can no longer afford to live there because they lack the wealth to outbid incomers. Maybe that's not quite in scope for "tourism".
I can imagine other issues, like facilities being tailored to richer people (all your green spaces get turned into golf courses, or whatever, all the pubs cost a fortune); teachers, services workers and such can't afford to live locally.
Richer people maybe cause more environmental damage? 3 cars, private plane, large concreted property, ..., yes at a holiday home, as one goes further up-market?
Perhaps good if you want to work in service industries.
