The Sands Hotel and Casino is seen in the opening montage of the Las Vegas Strip. The Sands was also featured in "Lucy Hunts Uranium" a 1958 episode of "The Lucy-Desi Comedy Hour." Lucille Ball and Desi Arnaz were invited to the Sands' fourth anniversary party in 1956.
Craig notices that Dean Martin is playing at the Riviera. Desi Arnaz Jr. was in a band with Martin's son. Martin guest starred as himself (and his doppelganger) on "The Lucy Show." His opening act at the Riviera is comedienne Totie Fields, who will act on a 1972 episode of "Here's Lucy." In 1975 she was one of the comics to roast Lucille Ball on "The Dean Martin Celebrity Roast."
Harry's 1970 yellow Plymouth Satellite convertible was previously seen in "Lucy and Viv Visit Tijuana".
On "The Lucy Show," Lucy Carmichael and Viv won a trip to Sin City in "Lucy Goes to Vegas."
The rear-projection shot of the cast driving down the Las Vegas Strip is visually similar to the now iconic image of the Ricardos and the Mertzes driving across the George Washington Bridge singing "California, Here We Come!" on "I Love Lucy," which was the first process shot used on television.
