We have reserved __ seats in your honor rsvp

I think you'll be ok - I would guess that many will write two names when two are invited, three when it's three, etc. Anyone who you're confused on, just reach out to them directly.

I would think everyone would write the names attending on the line. If there is confusion just give them a call

We actually added a note in our invites asking people to ensure they tell us the number of people they accept (we had the accepts blank seats line) and to provide names of those attending.

We just did that because we know our audience lol

I think you'll be fine. Don't sweat it--they should know to write everyone attending's name on the line.

The same thing happened to me! Most of my guests put the number attending and if they didn’t, you can pretty much assume based on how you addressed the envelope!

I think they will fill in the information

I think it'll be fine. If it makes you feel better, I actually got one back Friday that had no names on it! Our RSVP actually has the word "name" ... So even if you change it, it may not even make a difference. Don't sweat it.
