How do you handle a plus-one who is not your guest's partner?

When a guest asks to bring someone who is not their partner, think about your numbers and budget first. It is fine to say yes if you have room, and it is also fine to say no. If you say yes, treat the plus-one exactly as you would any other guest. Send them their own invitation, or at least a clear note with the date, venue, and dress code. Ask about dietary needs and any access requirements. Seat them next to your guest so they feel comfortable. Introduce them to people at the table, and make sure they are not left alone while your guest is busy with wedding party duties.

If you cannot offer a plus-one, be kind and clear. Say that you are keeping the guest list close, and that you look forward to celebrating with them. Do not make them feel guilty for asking. Some guests will bring a friend because they do not know many people at the wedding. If that is the case, you could seat them with a friendly table and let the ushers or hosts know to look after them. The key is to make every guest feel welcome, whether they are a partner, a friend, or a new face.
