“Letter” to guests with invite?

I think if FMIL is insisting this happen (because you and FH don't have enough to do the night before your wedding), then SHE should be the one organizing it, and letting folks know about it. Having said that, I don't think it should be printed on your invitations. I'm with you on that point, you aren't hosting it, you aren't paying for anything, and you aren't collecting RSVPs for it. I do think you could include that information on a detail card that goes with the invitation, and of course, put it on your website. I like the wording of your sample letter too.

Don't let FMIL bully you about this. It's one more thing that is nice, but totally unnecessary. Focus on what is really important. Good luck.

I think that it'd be okay on the back of the invite, or a separate "details" card.

If there is already something on the invites directing guests to your website, I don't think I would mention anything about it on the invitation but be sure that all the information is on the website. Between the website and word of mouth, I would assume the word would reach everyone. If you do want to include something on the invitation, I would have it on a separate insert vs on the back, in case people don't look on the back.

Are you providing welcome bags to your out of town guests in their hotel room? If so, that would be a good spot to put it.

I totally agree that if you are not hosting it, it should not be included in the formal invitation - that gives the impression that are you hosting it. If your FMIL feels so strongly about it, I agree - she should host it.

I agree that I wouldn't put it on the invite. Back of invite or separate detail card if at all. I like the above wording above, however I would try to add no-host somewhere in the description, as I think if I read it with the invitation I might think that this was something that B&G was paying for, for the out of town guests.

I agree that it should not be on the invite itself. Tacky. I do like the idea of your little letter on either the back of the invite OR separate. I wouldn't put it on the back of the RSVP because they will be sending those back to you and will not have it to reference.

I would not put this on your invitation or even the back of your invitation. In fact, I would not add this to a details card either. The reason is because it appears as though you are inviting them to something that you are hosting. The expectation is that you will pay. You can put this information on your website and spread it by word of mouth. Anything else would create an expectation that they are invited to a hosted event.

I wouldn't call it a welcome dinner, because you are not hosting (and thus not welcoming). I'd say something more like, "Some of our guests are having dinner at X Place at Y time, and we will be dropping by to greet them. You are welcome to join them if you like."

We're doing something similar, I made it a separate event on my wedding website (through Zola, not WW, but I'm sure WW has as similar feature).

As a warning, we were initially thinking it would be similar to you where it would be casual and not hosted, but once we realized how many people we were going to invite, we ended up booking a space at a local brewery so people would have somewhere to sit and there would be some order to it.

I personally don't think you should do it if you won't be there for the entire time - what would be the point, people are there to see you and your SO.

That sounds pretty good to me but I don't really understand the point for it all... But All I can say is you just do whats best for you. Don't let anyone tell you what to do
