If you thought once the kids hit adulthood, then the family trip was done, you'd be wrong.

Research shows multigenerational holidays and large group family trips are a popular trend.

According to the Family Travel Association - over 50% of parents say they're planning to travel with both their children and kids' grandparents.

And a new trend study by an international hotel chain... found that skip-generation travel is also popular....  That's when a grandparent and grandchild book a trip together... and leave the parents at home!
