A wedding-level yes does not explain whether someone will join Friday drinks or Sunday brunch. Write down the events, their audiences and the counts each supplier needs. Use groups for a shared audience and review individual invitations for exceptions. Keep a family dinner out of the schedule of a guest invited only to the ceremony.
Aisle supports guest groups and per-event invitations and replies. Its guest site shows the schedule relevant to the guest. This is the organizer setup guide; guests looking for how to answer an invitation should use the guest RSVP guide.
