I do not think the Monarchy has any place in today's society, I have said it before that I don't believe people should be born into their situation, much like the offspring of famous people. The Queen has little control over anything any more so the absence of a Monarch wouldn't chance things much.
Thats aside, I am fed up of the News and Newspapers being polluted with things about the Royal wedding. It is impossible to escape.
That said, I do think William and Kate are nice people and very grounded and I hope they have a nice day and happy marriage.
