We just came across this really cute online Guestbook Store that customizes your guestbooks for every occasion down to how many pages you need. It is a really cute, personal guestbook. You can draw a picture of the couple, give your own special advice, write down qualities of the bride and groom, make predictions and just really have fun with it. They also have a wide variety of album covers to choose from as well. I think guests will have a good time thinking of stuff to write and the guest(s) of honor will love sitting down and reading them after the party is over.
Check out Guestbook Store.
