Okay so I just started receiving my rsvps in the mail and I already got one that has an uninvited plus one. I specifically addressed the envelope to just my friend, there is a large group of friends thats I invited that I did not include plus ones, didnt even think any of these people would have thought to bring a plus one. Do I call right away and let them know that it wasnt intended or do I wait until I have more rsvps in to see if I have any no's where I could accomodate these extra guests. I obviously dont wasnt to be rude, but my venue only holds 150 and thata exactly what I invited. Help!!!
