With the economy the way it is now days...honestly not a chance...why go to a snobby wedding? I mean if you must see it just wait some photographer/camera people will get you your fix I'm sure.
So no....I would guess only the "too rich for there own good" crowd will be the only visitors!
Its history. lol If you stayed up like I did to watch the Prince Charles Lady Di wedding you would know that this one will be a big deal too. But for commoners to fly over the pond just to be there, naw, only if i had an invite lol
