"Swinging" comedy has family from the suburbs getting duped by a low-rent travel agent into taking a cut-rate European vacation. James Garner and Debbie Reynolds would seem to be an ideal screen match, but this leaden script never gives their union a chance (and both are saddled with deadening lines like, "Stop fiddling with your necklace and act like a man!"). Garry Marshall and crack comedy writer Jerry Belson adapted the screenplay from Muriel Resnick's book "The Girl in the Turquoise Bikini", and veteran comedy director Jerry Paris helmed the proceedings, but the results are bathetic; comic support from old pros Paul Lynde, Marcel Dalio, Terry-Thomas and Vitto Scotti doesn't help much. These are not the "Happy Days", although there are fun bits by Erin Moran and Penny Marshall. *1/2 from ****
