Our wedding has hit a major snag! We've had to move the date and venue four months out of our original wedding date.
The big problem is, our new venue can only fit half of the guests we originally sent save the dates to (and who came to our engagement party). We haven't sent the invitations yet, especially since those reflect the old date and location, but we now have to notify our extended families that they are no longer invited.
What's the best way to do this?
