My fiance and I got engaged in May, and our wedding will be in August. I know typically save-the-dates are sent out around 6 months in advance and invitations usually 6-8 weeks. However, I will have a lot of out-of-town guests, and my mom said it's not too soon now (11 months before) to make some sort of announcement - i.e. a private Facebook group or something, because many people will be planning their summer vacations already.
We have the venue booked and there are some people I've personally told the date to, but to me it just seems too soon to start announcing it to everyone. So for someone with a lot of out of town guests (cousins and long distance friends), when should I make an informal announcement? And would creating a private Facebook group be a good way to do this? I don't have most of their mailing or e-mail addresses, and am only in touch with them on Facebook.
Thanks!
