So my fiance and I made the decision to invite all of our out of town guests with a +1 - we thought it would be nice if they had to travel for the wedding to have a companion. There was one exception though - I have a younger cousin, and although he is a nice guy, he always ends up with a random girl for a few days to a few weeks at a time and then never mentions her again. Sometimes there's serveral in a month! I really don't want one of these girls to end up at my wedding, so although he is coming from out of town we invited him solo. Our RSVP cards actually say "___ of ___ guest(s) will attend" and then we filled in the second blank, and in his case with a '1'. Well I just recieved an e-mail from him this morning informing me that he is definitely coming to the wedding but hasn't sent back the RSVP because he is unsure of whether or not he will br bringing a date... HELP! What do I say to him? He will have some family also travelling down for the wedding - but they were all invited with their significant others or a +1.
So do I explain to him that only he is invited?
Do I tell him I need to know by June 8th for sure because that is the RSVP date?
Any better suggestions??
