I sent out my STD's about 2 weeks ago. I'm not too concerned about the invites, but once I get all of the details nailed down such as rehearsal dinner (we're hosting everyone since it's a pretty small group) and menu choices, I'll probably start worrying about them. I feel like it's more of a formality in terms of the invite and more of a way to get information to everyone about what's going on when. We will do an RSVP, but the big thing is that we're having a plated dinner and we need to get people's choices before they get out there. As we talk to people, we're getting a sense of when they can start booking (unfortunately, everyone needs to put down the full flight when they book, not just a deposit, and it's not as easy to get that kind of $ free around the holidays for everyone). I want to start OOT bags so badly, but I'm holding back until I know how many I'll need. I don't want to overbuy or have to go back and try to get more.
