After a long afternoon in Budapest’s Varosliget park, we wound up almost by chance at Vajdahunyad Castle, where we had our wedding party four years ago. Diana was only there in the womb back then, and Esther wasn’t even a twinkle in the eye. This time, Diana romped and played like crazy with other children at the lakeside cafe. The place is just as magical now – even more, if anything.

The weird Portakabin in the middle of the lake is a real toilet – a sculptural installation of some kind. How’s that for added romance?
