Karen Sue Trent, about age seven (appearing as Joan in this film) went on to guest star as "Penny Woods" in 14 episodes of Leave It to Beaver four years later.
When he realizes a professional mechanic is required, he invites Susan and Joan to rest at the nearby Garden of Eden resort until a garage opens.
After making them comfortable in a cabin at the "members only" resort, Johnny leaves to arrange to have the car worked on, but fails to advise Susan and Joan that they are in the middle of a nudist colony.
After Johnny discovers that the car repair will take several days, Susan, fully dressed, wanders outside to meet several of the nudists, including a theater director, who expresses an interest in her acting ability.
When Susan wakes up, Johnny is there with an update on the car and she tells him that that evening the director has asked them to perform a scene together from Shakespeare's Romeo and Juliet.
Early the next morning, unaware that he is in a nudist camp, Lattimore leaves his cabin for a stroll and meets the theater director, whom he recognizes as a famous Shakespearean actor, but is stunned when the man goes swimming naked.
Later, Lattimore meets Johnny and apologizes for his conduct the night before and, after wandering around the camp and observing how relaxed everyone is, becomes enthused about nudism and decides to become a member.
