The Last Resort (1986)

Synopsis
George Lollar (Charles Grodin) overrides his wife's judgment and takes his family for a vacation on a sunny Caribbean island that just happens to be on the verge of a revolution. Their hotel is not the usual Hilton on the beach but a pick-up joint for singles where the main activities are sex, sex, and sex. In that order. As the horrified father watches almost helplessly, his wife becomes liberated, his daughter falls for a Frenchman who is actually a guerrilla, one of his sons loses his virginity to a buxom, worldly-wise woman, and his other son burns down the mini-camp he was forced to attend. But that's hardly the worst of it -- there is that small matter of a political overthrow about to explode on the scene. ~ Eleanor Mannikka, All Movie Guide
