I just searched for you.
I can answer for Mykonos
2 very professional and big camping sites, knew both the business very well.
I would think all camping sites are well organized and managed well, they get a lot of camping and caravanning traffic from the European neighbors.... Enjoy!
My cousins are Canadian and they just let me know that you can now book flights to leave the country (and finally go to Greece!) without having to hotel quarantine upon return. This is so exciting because I haven't seen my Canadian cousins in three years and they'll be finally visiting me in Athens this year.
As of now, there are very few direct flights from Athens to Toronto, so I need to stop over in Europe on the way to my Greek vacation so I don't want to have to stop in Athens before flying to an island. Are there any islands I can fly to directly from Europe?
