Blended (2014)

Single dad, no clue. Single mom, flying solo.

Recently divorced mom Lauren and widowed dad Jim let their friends push them into a blind date, which goes disastrously wrong. Unsurprisingly, neither wants to see the other ever again. However, fate intervenes when both Jim and Lauren, unbeknownst to each other, purchase one-half of the same vacation package at a South African resort for families, during spring break. They and their children are forced to share the same romantic suite and participate in a slew of family activities together.
