Please advise your venue you have hired Once Upon A Prop and to please have a large enough area near a 120 V standard 3 prong outlet ready for us. Traditional photo booth dimensions set up for an enclosed photo booth are 6x6 all around with 7ft height and a 6ft table butted up against the camera boxes....see photo to give you an idea of space needed.
Open air photo booths don't require as much room. We have 7FTx7FT backdrops with our 6ft table placed infront of the backdrop. Please see photo below for example.
