So we are getting married this weekend 3/30/19- and of course AFTER we finished paying off our venue and final numbers were in, we have guest that have RSVP'd but are not able to make it- we are very understanding and they offered to compensate for the meal - but of course we said no. With that being said, we are paying for a meal for someone who won't be there so I was thinking about inviting someone else. Is that considered rude? The person I want to invite is a friend of a friend. Im a pretty straight up person, if they ask I will tell them someone cancelled and we have an open space, but I don't know if that person will take into offense being invited last minute just because someone cancelled. Thoughts?
