Should I list everyone on the STDs? We are inviting children of family and everyone will have a plus one. The plus ones (meaning dates for singles, not SOs) I would ideally leave off just in case something happens (with everyone getting a date we are at capacity and you never know if we will think of someone else we are missing or something), but I don't know if that will make it harder for everyone to plan if we wait until invitations go out to include "and guest".
