<human>: A quick question that has been causing me and my fiancee some issues lately. 

My FH has an extremely large family, split between two different states (over 50 people between both sides of his family, easily. Probably closer to 75, but I don't feel like counting). I have a relatively small family (under 20 people). We have decided on a reception venue that only holds about 80 people. We've also already decided on the guest list- all of my family, all of his family that lives in the same state that we do, and a bunch of friends. We are also planning on traveling to the second state, specifically to party it up with the rest of his family that we can't afford to host. 

The question is, we need help coming up with an insert to put into the invitations of the family in the second state, that pretty much says "we really don't expect you to make the trip, we've already celebrated with you, and this is really more of an announcement then an invitation."

Can you condense the text into three sentences or less?
<bot>: how do we break it to part of the family that they aren't really invited to the reception, because we've already celebrated with them and we have no room?
