Second Honeymoon (2000)

Maggie (Roma Downey) and George Weston (Tim Matheson) have decided to call it quits after a long 20 year marriage, but decide to keep it under wraps for now.

However, when their parents and kids surprise them with a non-refundable second honeymoon on a tropical Caribbean island for their 20th wedding anniversary, the feuding pair are shocked.

They decide to take the trip, but agree to spend their time apart on the island. Once they arrive, Maggie catches the eye of a handsome local, while George sizes up a leggy blonde and absolute hilarity ensues.
