Is the rehearsal dinner mandatory? Simply put, my family is not the richest in the world and we are spending a lot of our own money on other, more important stuff for the wedding. His parents are already helping a lot by paying for almost the entire cost of the food FOR the wedding. We thought of cheap places to go but the wedding party has 10 people in it, including us. Is it rude not to have one? Any thoughts on what could be done instead of one? Or does it even matter to begin with?
