I think the point is that if a head of state or PM is at an official residence they can still carry out the full range of their responsibilities. I am not sure that wandering (ineptly) round a Greek supermarket provides quite the same opportunities.
Theresa May visited Macron at the Fort de Brégancon when PM. It is a wonderful historic fortress near Bormes-les-Mimosas right on the Mediterranean.
Apparently the Fort can be visited when the President isn't in residence. A friend taking a holiday in Provence a few months ago visited it - an amazing location.
That is why I do have sympathy with ALL our PMs and their exotic choices of holidays. Blair used to escape to Tuscany, Cameron to Ibiza, Theresa May to the Italian Lakes. Chequers is, I am sure, a beautiful place with a huge estate, but holidaying in the Chilterns doesn't really compare with being on the Mediterranean with sunny weather, good food etc. Unfortunately British PMs are hard done by on that front, especially if they want to feel energized from their summer break.
I think it was only Thatcher who considered holidays a distraction from the primary task of running the country, and look what happened to her!
