A.
You may send invitations to those
in the wedding party if you want to, particularly if they have a
family that might be coming to the wedding and reception. You
will need to include all of them in the count that you give to
your caterer. The ladies in the wedding party particularly like
to have an invitation as a keepsake. If an attendant is single
and you know they will be coming alone, you don't have to send
an invitation if you don't want to.
