It was directed by Roy Rowland and based on a story by John Larkin, who co-wrote the screenplay with Dorothy Kingsley.
Patti (Jane Powell) and Melba (Debbie Reynolds), the daughters, are both accomplished in the performing arts, while the Robinson boys love fireworks and mischief.
The Robinson family is at the Stanley House Hotel, located in "Kissamee-in-the-Catskills", a resort town, for their annual two-week vacation.
Patti and her friend Valerie (Phyllis Kirk), a slightly older actress, compete for the attention of Demi (Ricardo Montalbán), a handsome Cuban newly arrived at the resort.
