I like the idea - but my guests loved the instant gratification of being able to have them in hand and being able to print them later (or tag them on facebook.) Just a thought. Sounds great, we actually loved the black curtains and it was always a game to see who we thought was in there.
We booked Redeye for the same price- 4 hours, color photo strips with our wedding date printed at the bottom, and instant photo strips for guests to take home with them. Just for comparison I would suggest giving them a call. Photobooths are awesome!
