The attendees from year to year are a rotating cast of the
extended Danish family, whichever members happen to be staying
at the castle at the time, I guess. This year, Queen Margrethe and Prince Henrik
were joined by Crown Prince Frederik and Crown Princess Mary and their
kids (Prince Christian, Princess Isabella, Prince Vincent, and Princess
Josephine), as well as Princess Benedikte's daughter Princess Alexandra
and her family (husband Count Jefferson, plus kids Count Richard and
Countess Ingrid). And an assortment of dogs, obviously.
