Thats about £150,000 / €174,000. That is alot and makes me wonder whether quietly behind the scenes there may be pressure for such holidays to be reigned in from now on.
Harald and Sonja deserve a nice break, of course they do, but maybe somewhere a little closer to home next time.
Medical evacuation can be very expensive especially from far away places. EUR 174K is typical. That could bankrupt an ordinary person. That's why they tell you to get travel insurance when you travel.
As privileged as they already are, royals should be able to take private holidays. They live so much of their lives publicly that it's probably mentally taxing.
And H&S intend for their private holidays to be private. They don't alert the paps, etc. The heart situation was an unfortunate turn of events.
However, given H's health struggles in recent years, he shouldn't be traveling far from home anymore. Sure, he must think he's still mentally young, but his body is otherwise.
