Table set up with maracas on each place setting. You can see the tiki torches and lounge area in the background. On each table we also placed a disposable camera with "Camera/Photo Scavenger Hunt" instructions.
So, instead of a traditional guestbook, we had a white eraser board and markers and asked guests to write a message on it: words of advise, a happy memory of us, or a favourite moment from our wedding. They were then to snap a photo before passing it along to the next guest. Here I am getting in on the action.
ETA: I wished someone had told me the wind was blowing my bird-cage the opposite direction!
