I want to put disposable cameras on each table at the reception, but am not sure what to do with them next. Should I leave notes attached to the cameras that give instructions on what to do and where to leave the cameras at the end of the night? Has anyone done this or planned on doing this? How do you keep track of the cameras at the end of the night? Maybe say, when the film has run out, please place somewhere? Sorry I'm a jumbled mess in this post. Any suggestions? TIA
