I am planning a renting a photobooth and I am not sure how long I should rent it for. I was looking at this one company that does 2 hours for $500, 3 hours for $700, or 4 hours for $900. What is everyone's recommendations. I honestly feel comfortable financially with the 3 hours for $700 but I am not sure if three hours is going to be enough time. What does everyone else think?
