Did you do a separate box on RSVP for # of guests attending?

For the one family so far that has split attendance, they marked it clearly so we knew one would be coming and the other couldn't. But we had the M________, then the # seats reserved, then Accepts/declines. It's worked for us so far. For the couple that was split, they crossed out the 2 and put one (for attending) so it was completely clear. We already knew the wife couldn't make it, but that was really helpful.

We did the same format but did not put a space for number attending. Guests put that on the accepts/decline line. So if 2 seats are reserved and only one attending they put 1 (name) accepts 1 (name) declines.

You can do everything in your power to prevent mistakes, but you will still have to call and follow up with people.

Number your response cards. That way if someone leaves the name section blank you still know what household it relates to

Under "accepts with pleasure" we put a line underneath that says "Number attending: __ "

Following

We are wording it as such: A total of ____ guest(s) will be in attendance.

This way, the guest can fill in the number.

I just sent it the RSVP for my cousins wedding. It was worded similiar to yours and I just marked a 2 next to attending (and only 2 of us were on the invite).

Yeah I would make it clear somehow that they have to include themselves! I had several guests check thrilled to be there and then a 0 for number of guests. I figured most people knew what that entailed but I was mistaken lol also shout out to my guests that had plus ones and wrote their own name only! And then put 2 -_-
