“Boggle” (Sid James) and his partner “Fussey” (Joan Simms) plan a camping trip alongside their friends "Bernie" (Bernard Bresslaw) and "Anthea" (Dilys Laye). The men mistakenly believe they’ve found a nudist campsite, but quickly realize their error. After being swindled by the site's owner (Peter Buttherworth), they get caught up in several misadventures that lead them to encounter Kenneth Williams ("Dr. Soaper") and Hattie Jacques, along with a group of young nurses on a hospital outing. The story progresses predictably as this suggestive, physical comedy unfolds, incorporating humorous situations drawn from everyday country life. While the jokes are fairly obvious, I thought it was one of the more enjoyable films featuring this cast. It frequently veers into broad farce and maintains its characteristic level of cheeky humor—plus “Babs” (Barbara Windsor), "Peter" (Terry Scott) and his camping-loving wife "Harriet" (Betty Marsden) contribute noticeably to the secondary storylines, which enhances the overall entertainment value. I’d place this among the stronger entries in the series, and there's even a goat!
