They both have a history of working for humanitarian causes and if they, as a couple, can use the clout they will have to further these causes, then I applaud that. Better than sitting back and wallowing in their status and wealth.
As with any young couple embarking on marriage, I wish them well, even though maryeliza might see that as "shallow."
There are plenty of examples of royals who do not have their integrity. We should be pleased at their vision and pleased for their happiness.
I am no royalist, but I think we have here a better example of what this can mean.
