I think the girls should get together and decide how much they are willing to pay to go. Then ask the parents for their imput, want to bet the parents go for the cheaper theather? Now if it were my daughter I would put foot down and say it is the $6 movie or none that night. Once the movie starts who even notices what the place they are watching it in looks like? This is a good example to also teach the kids how to live furgle and there for have more. Good luck, take care.
