I work in an office of 12 people. We our spilt into two invited "my side". An employee on the other side is already invited because her and her husband are family friends. Do I invite the rest of that side, even if i can't control who their plus ones will be. (I've heard about previous invites from a co worker). Don't care to invite 2 people. All or nothing? Not sure what to do. Any suggestions? Thanks.
