Instead of a guest book, try a polaroid scrapbook. Make sure the polaroid camera has plenty of film. Wedding guest can strike a pose then leave their photo on the guest book, together with their short message for the couple. INSTEAD OF GUESTBOOK IDEA
Guest book idea - great because you can get a photo of everyone at the wedding and get some advice for a scrapbook. Such a funny idea. It'd be fun to combine this with a photo booth. A photo booth guest book.
