I agree, I would like to see Prince Constantijn and Princess Laurentien more. I expected to see them in glitter and glamour at the Chinese and Swedish banquet. But okay, I don't think that Queen Beatrix will attend all State Visits.
Since Princess Margriet has 'retired' then this is the moment for Prince Constantijn and Princess Laurentien to appear. We will see. And in 8 years time we will see HRH The Princess of Orange reaching the age of consent, that means she will start her public life, I guess...
