We have a pretty large group of mutual friends. My question is, if there is a single person we are wanting to invite and we know they will have plenty of people they know at the wedding do we have to allow them to bring a guest anyways? I dont want to seem rude but I would honestly like to invite more people I know instead of making alot of extra room for dates. And if we dont have to allow a guest, how do we approach someone if they try to RSVP for 2 people?
