My wedding is in 2 months and invitations are going out within next week. I know that some are already RSVPing No and there are some people that are just aquaintances that would love to be a part of my day and I would like them to come if I have the space but of course they weren't originally invited. So when I get a better count on whos in and whos out do I have to send these so called "b-listers" invitations? I don't have any extras so I rather not, so do I just verbally invite them?
