Since the Hartleys vacation is a sixty-day cruise, it's likely that this episode was planned as the last episode of the season; however, it ended up being the second to last. In the next episode, there is no mention of the cruise or sixty days having passed.
Archie Hahn, who plays The Steward in this episode, also plays a similar role in Season 1, Episode 11, "I Want To Be Alone". In that episode, he plays the bellman.
The title is a parody of the French phrase; "Bon voyage" - 'good journey'. and is said when someone leaves on a trip.
