Activity for Julie

What is a good song for the groom and mother to walk down the isle ? And also what’s a good mother son dance song ? I need some ideas . Also a song for the bride and groom to walk away to? After the ceremony

Bride and groom first dance. Then the father and bride. Mother and groom. Then in laws with bride and groom right??? Then do we have our parents dance with each other?

Does the usher seat the families before the groom walks? Then does the groom walk down and wait for the wedding party to then walk.?

What is everyone’s best advice on shrinking your guest list?
