I don't think Balmoral/ Braemar area is quite as fashionable as a ski resort. I think the children attract photographers - but, actually, why haven't the Prince of Wales's children - George, Charlotte, Louis Bern photographed a lot at Anmer House and environs?
Maybe it was Diana herself who drew the interest of the press towards her - her magnetism for the hordes of avid fans, watching to see what new and sometimes daring and different thing she would do next.
Well I suppose Will and Catherine have got it about right in their management of their work - because they are not really hounded by the press or fans.
Nor is Kate's sister, Pippa. Her wonderful figure once promised her a devoted following and a star profile - in the aftermath of the Royal Wedding. That has dissipated and subdued to mild interest and the odd article. It has worked. I bet she is happy. Nor are the Middletons hounded. Keeping a low profile has been a success all round and not too much intrusive attention. No disgruntled former staff selling stories about Party Pieces, either.
I don't know about private ski slopes and hillsides on private land. I bet there are some.
Where do the European Royals take their skiing fix? Actually, why are they not hounded?
Seems like keeping it on the low and private keeps the personal things private too.
Termly boarding school at somewhere traditional, like Eton, is not what most people would call normal everyday life. Weekly boarding, maybe more so. The Royals are already making somewhat rarified choices.
