Pick Four Royals For A Dinner Party!

[Nice Nofret]

Prince Phillip for the fun
Grace Kelly for her beauty
Queen Margarethe for the interesting conversation
Camilla for good fun

I'm pretty sure I've done this already, but will give it another go:

Queen Maxima - for her fun and vibrancy and to show us how to dance a tango!
Duchess of Cornwall - I'd like to know more about her, her personality etc
Empress Michiko - she can play the piano after the dinner
King of Bhutan - to tell us more about his mysterious country

Naturally they could bring their spouses along too!
