Ending the night without dancing

I am getting married in a few weeks and we are not doing a dance floor due to COVID concerns. We are planning to do first dances (bride/groom, father/bride, mother/groom). After talking to our DJ, he recommended that we do one dance for everyone to get on the dance floor because the transition between mother/groom dance and the send off isn't super smooth. My FH is NOT onboard with doing a group dance, but I'm not sure how to bridge the transition between the mother/son dance and the send off. Would it be weird to have a final song and encourage people to just dance at their tables? Any recommendations on how to end things? (Note: We're serving cake before the first dances.)
