Due to the capacity of the venue where we are getting married my FI and I decided that single guests did not get a plus 1 in order to keep our numbers under. We did however give single WP members a plus 1.
My problem is that our one WP members roommate, who is single, RSVP'd saying that it is just for him but he is going to use our WP plus 1 if he does not bring a date. My issue with this is that other single people who were invited did not get plus 1's and the only reason why single WP members do is because of the role they are taking on in our day. So basically what I want to know is it rude to tell our guest that plus 1's are not transferable?
