This was the first of several bikini movies made by Annette Funicello and Frankie Avalon back in the s, a genre which petered out pretty quickly, thank heaven. Bob Cummings and Dorothy Malone were given top billing despite their relatively minor parts, and Vincent Price has a cameo. There's not much plot. Frankie and Annette are spending vacation at a beach house. He planned to be alone with her but she invited a dozen or so others to act as chaperones. Most of the girls wear sexy bikinis, but Annette wasn't allowed to because she was a Disney girl.
