My one question about 70s key parties is just logistical: how did they all get home the next day? Like, did the husbands drive the guest wives back to their own houses, or did they go to pick their own wives up?

Did they have to coordinate so that everyone would be ready at the same time so you didn’t have to talk to the person your spouse just fucked in the sober light of day, or risk walking in on them going for a bonus round?
