Strange-looking alien fugitives alter their appearances to look human (but not at night) and hypnotise the now travel-agent Mr. Zumdash (the mouth-popping Fritz Feld, back for a third appearance) into taking them down to the Robinson's planet as tourists, prompting the ever-mercenary Smith to convert the Jupitar 2 to 'Happy Acres', a holiday-resort. With a thin, contrived premise, silly props (notably Zumdash's interplanetary golf-cart and Smith's assorted 'sporting equipment'), and strained slap-stick, this is not one of the series' better episodes (even judging by season 3's low standards). The episode is also at odds with earlier episodes (aliens have been free to come and go for the last two and a half seasons planet but now they need the Robinsons to activate a landing beam if they want to touch down). The most interesting part of the episode is the casting of Edy Williams, perhaps best known as playing Ashly St. Ives in the camp-trashy 'Beyond the Valley of the Dolls' (1970) as a seductive space-babe (she's a natural). Add wicker arm-chairs and an old-fashioned cash register to the Jupiter's strangely diverse payload.
