I figure this is the best place to post this. My future in laws are always neglecting to tell me when they find that some of thier guests have decided to bring more people. My parents and myself are the ones footing the bill. They do not tell me when they invite someone else and do not seem to care that they have almost made us pass the 200 person limit I set. how do I politely tell them that if they want to invite people, thats fine, but I need to know? and also that they cannot invite more people if they make us hit the 200 mark?
