I was browsing the web and I found this unique idea to have at your reception. A "Snap" Station.
It's a table full of different cameras and the guest can pick them up, snap photos and put them back. Can you imagine all the silly and fun pictures that you discover once you develop the film after your Big Day! It's a new spin to just putting disposable cameras on the table and if you are having kids at your wedding you can put a few black and white cameras on their table as another activity to keep them busy.
Just make sure you use cameras that you wouldn't mind if they get broken, as accidents do happen. *shrugs*
You can search eBay, Craiglist, Freecycle, Yard Sales, a relative's attic or basement and many other places to find cooky cameras for your table.
This is one idea I'm thinking about using. If I can use my resources to find super cheap cameras (which I'm pretty sure I can as I consider myself a princess of bargin hunting! Toot Toot!)
