We're doing a rehearsal dinner but it's going to be a pretty low key event - cozy local restaurant, buffet style late lunch, not a huge guest list. FFIL is throwing it and FI is organizing everything for him. Together, they decided they wanted to send evites instead of paper invites, which is fine by me. The only issue is that we're now unsure how to word things to make sure that everyone knows their guest is also invited. We don't have the email addresses for all the plus ones or SOs, or even know if everyone is bringing a guest yet, as our RSVP date for our wedding is 3/17 (RD invites will need to go out before that, though, as we need numbers to the restaurant by 3/24). Right now, FI has "you and your guest are invited" but that seems odd to me - I don't really want people to think they can just bring guests who aren't invited to the wedding or something. Any idea what the best way to word this is? Or should we just send it out without a mention of guests and let people know, word of mouth, that SOs and dates are of course invited?
Another question is that while it's mostly just people who are involved in the actual rehearsal invited to the RD, we have a few family members that FFIL is inviting who don't need to come to the rehearsal. Should we send a separate invite for when the rehearsal is? Or is it fine to just let the people involved in that know via a personal email or call?
