Photobooth during reception

I am considering getting a photobooth to come in and to be available after final speeches/dessert is served for a couple hours. A lot of the guests attending are younger (late twenties/mid-thirties) and I am thinking that the photobooth would be set up across from the bar. My concern is if anyone would use it. For those that had a photobooth at their reception, was it used? Were there a lot of people who used it? Was it worth having it there?
