John Candy sure wasn't having a whole lot of fun during his free time, and neither will you and I. SUMMER RENTAL is a relatively harmless "family" comedy with unexpected situations that can go haywire or just perfectly normal. Of course, the long-late Candy is excellent at being an idiotic screwball, which best fitted his own personality. He alone is what makes this worth the fun. Otherwise, it's pretty flat and monotonous all the way through. Take a trip to Miami Beach and your summer vacation will be far more pleasant. Joey ("BLOSSOM") Lawrence looked very young on screen, though!
