We used Digital Expressions for our December 18, 2015 wedding. They were easily one of the best vendors we had the pleasure of working with!
Laura and her husband are SO easy to work with. They look at floor plans of the location and offer suggestions of where they should set up the photo-booth and bring such fun props! Not only do you get printouts and a photo album (in your colors!), you also get a Google Drive gallery of all images and a CD as well.
All of our friends had a blast using the booth and the pictures are such a great keepsake because we can see how much fun our friends and families were having--especially helpful in the craziness of a wedding where you're not able to spend lots of time with people.
ALSO, the value for the price is unmatched. I am not convinced they're charging enough!
