I think something like this is a Must. We can make a designated backdrop or area for every quest to visit to have their pics taken so you can see everyone who came to the wedding. Should probably be near the entrance or the reception?
First comes love, then comes marriage, then comes the home :) I love the idea of starting "our lives together" with a barn theme wedding, then moving to Texas to work with Joanna and Chip on our barn theme home. Now that's a dream!
