So FH and I sent out our invites this week! It was very exciting. A few people close to us have already received theirs, and I even got 1 RSVP back already. So exciting! 
Anyway. To avoid people bringing random dates and the whole confusion on if they get a plus one or not, I figured I would make it very clear and use the "We have reserved ___ seats for you" on their RSVP card. We gave pretty much everyone a plus one, so it usually said 2 seats.
Already, THREE different people have come up to me and said, "So does this mean I can bring 2 people? So me and 2 others?" WHAT. On what planet does it mean that?! grrrrrr
So I hope I don't get RSVP cards back with 3 names on them... I don't wanna have to call all these people and set them straight! Anyway just wanted to vent... Has anyone else had people assume they can bring 2 dates? LOL
