V.W.
I agree with Jo W. A horse drawn carriage is pretty unique and old fashioned.
But I am not sure I would want a "royal wedding" themed wedding... I mean, William and Kate are recent news and constantly making the news and probably will be for years, but, is that really what they will want their wedding memories to include? I don't think I would want to look back 15 years down the road (that's where we are in OUR marriage right now--at 15 years) and say: "Awwww..... look honey! We copied Prince William and his bride Kate! Isn't that so cool?" It just doesn't work for me. But hey, to each his own, right?
