Advice for those planning on doing DIY invites

OK so I went over and over wording my RSVP. I wanted to make sure noone would invite a guest if they weren't originally invited with one. I should have filled out the numbers on the respones, but didn't want to seem arrogant. So my RSVP said __Yes, accept with pleasure
number of guests___

__No, decline with regret

Turns out some people think 'guests' means how many people they are bringing!! I don't think too many people will misunderstand, but since there are a few who did, figured I'd give you a warning.
