We are having a very informal rehearsal dinner at my FIL's house. Of course the whole wedding party plus our grandparents are invited. Question: do I need to invite all the aunts and uncles? There's 27 of them. 6 are out-of-towners. We're on a budget, and that doubles our list. However, 2 are staying at FIL's house that weekend so obviously they will be there. What to do....just bite the bullet and invite everyone, or keep it the way we have it...?
