The wedding couple can make the in-law dances immediately following the father-daughter and mother-groom dances. Additionally, the in-laws can tap in mid-dance. If you choose this option be sure to coordinate with your professional DJ. It’s worth noting that the more formal dances you have, the more time guests are waiting to cut loose and dance themselves. I would recommend announcing that the bridal couple has a special song with their in-laws and inviting everyone to join in with their dance(s).
