I'm not religious so I don't think marriage is a feat of anything. I think it says "this is mine don't touch" and people see it as "I must have it because its forbidden." I'm glad they found one another though, as I am with any couple. Happy lives for all!
Time zones would be a problem for some, I understand. I had/have no interest in the royal family at the present; they haven't done enough here to be any different from any other incredibly wealthy celebrity couple being married, and the whole thing was WAY over-done by media. I didn't technically watch it, and generally tried to avoid the TV for the days around the wedding, knowing it would be everywhere.. >.>
ALSO, my cousin married her boyfriend in Ireland very close to the same date.. I was much happier for them since I actually know them and felt it much more meaningful
