The first picture is of a spinning game wheel.  Guests will be chosen to spin the wheel, and it will land on some kind of instruction either for themselves, or the bride and groom.  Next is the photobooth.  There will be an open spot with a backdrop, and a photographer with a camera.  The guest will find their name, and replace it with the picture they just took, and the bride and groom can keep it as a keepsake.  A sign will list all of the activities.  A bonfire would be a great activity for everyone to enjoy and talk around.  The couple wants an open dance floor, more specifically to keep the younger guests occupied.  Carnival-like games would be a perfect addition to an already fun and casual enviroment.
