We sent our save the dates out about seven months before the wedding, but we had only finalized the resort then. Most people did know the date and general area before that though, as we have a small group and had spoken to them about it. They had on it the date, the resort, and our website. Invitations just went out last week, but most people have already booked and the few people who may come will only book last minute anyway, so I thought it was better to send them closer to the date.
