I'm just going to come right out and say it, my family has a lot of money and my fiancé's family does not. That being said, they have much higher taste than my family. (We're a bunch of cheapskates.) Since they're paying for the rehearsal dinner, they want to have it at this fancy place. When my fiancé and I tried to talk to them about having it someplace cheaper, they were insulted. They were like "you only get married once, you're going to have a nice rehearsal dinner!" But we CAN have a nice dinner someplace else that has better food and is cheaper and that we like better. I really don't like fancy restaurants. They think they need to "impress" everyone. I have told them that my parents would be more impressed by them saving money instead of spending it (which is true), but they don't buy it. Any advice?
