Or don’t have them do a buzzstep—swings work just fine with a walking step. (If you’ve got moderately experienced folks mixed in, though, you may need to teach the buzzstep, since few moderately experienced dancers will do a walking swing even if asked to.)
If you do teach buzzstep, I’ve had the most success teaching it as a gallop

Getting them into ballroom position for the swing and then teaching them to let go of the pointy hands works much better than “gents on the left, ladies on the right” for ending correctly.
