So my wedding is one week away and we have already turned in our numbers for our head count and everything to our reception site for our meal. Turns out that a few (at least 10) members of my FI family who never bothered to RSVP told his parents that they were "just planning on coming to the reception." We gave ourselves a little bit of a cushion for meals to plan for extra people but we definitely do not have enough for 10. My question, or at least maybe some advice, is what do we do with the extra people that we don't have meals for? I know it's rude that they didn't RSVP but it's (at least in my opinion) rude to also not provide a meal for your guests. Help!
