I'm just inserting an opinion:
IF William is going to miss his cousin's wedding (who I've heard being call someone he "leant on" after the death of his mother), I will be very shocked, and a bit disgusted. Unlike a lot of people here I like Kate (I have my reasons!!), but it will really disgust me if she would go along with this when she made sure that William didn't back out of their date to her cousin's wedding after their break up last year. It just seems completely inappropriet to be missing Peters wedding for a holiday, no matter how long they've been seperated because of his duties (that's how it's going to be a lot of the time when he becomes Prince of Wales, and eventually King, so they might as well get used to it, and start learning to spend some time together IN THEIR OWN COUNTRY, possibly at home, watching TV or something, you don'ct have to be on a beach in the Carribean or the Med to have alone time together).
