WASHINGTON – The busiest travel time of the year happens between Memorial Day and Labor Day—that much is indisputable. But the other information about who’s vacationing, how they get there and how much they spend, plus where the best deals can be found, has been hidden under a cloud of misinformation, the Washington Post reports.

“The best summer trip for you may not be something that’s trending online,” said Zane Kerby, president and CEO of the American Society of Travel Agents. “The overall travel experience can be complex and highly personal.”

For example, not everyone goes on vacation, according to numerous studies. Surprisingly, one study found that less than half of American workers actually use all of their vacation time. Conversely, people aren’t unplugging from work even when on a trip. A Wrike survey discovered that 40% of men and 30% of women said they would be working while traveling.

The most popular method of transportation isn’t flying—it’s driving. The new NACS survey found that most travelers go by car (85%), then plane (36%) and train (8%). Plus, nearly a third of vacationers will drive 12 hours or more.

Not everyone plans ahead. More than a third of Americans still haven’t decided what to do or where to go on their vacation. Around 29% have begun making plans, but haven’t fully committed, according to a HomeAway survey.

Other myths include the belief that Americans are spending more money on vacations, but some surveys find that we’re actually shelling out slightly less than in previous years.
