A new survey revealed an estimated 99.8 million people will travel at some point during the 2017 holiday season.

The results also revealed 48 percent of millennials plan to travel during the holidays, the most of any age demographic. Fifty-four percent of people with children will hit the road, according to the consumer holiday travel survey from Generali Global Assistance’s Travel Insurance division.

The survey broke tourists into two categories; those traveling to see family and those taking a trip for vacation.

“For many, the holidays are an important time of year to connect with loved ones and going to see family is by far the primary reason to travel during the holiday season, with 87 percent of Christmas travel and 64 percent of New Year’s travel being dedicated to going to see relatives,” Generali Global Assistance CEO Chris Carnicelli said in a statement. “For those traveling to see family, becoming closer as a family was the primary importance at 68 percent, followed by relaxation (66 percent), reading or learning new things (18 percent) and sports activities (13 percent).”
