This is just a thought because invitations haven't been sent yet. We're giving a plus one to just about everyone who is invited to the wedding. The only people we were thinking about not inviting with dates is my fiance's work friends. There are about 6 of them, none are in a relationship, and we thought we could invite them without a date since they'll all know each other. Is that okay to do or will it be offensive because everyone else is being invited with a plus one? These people get along really, really well and are friends outside of work.
