Parents are still paying for their children's holidays long after they turn 18.
Nearly three-quarters of adults under 25 went away with their parents in the last year, with two-thirds getting a free trip.
New research from Enterprise Rent-A-Car also found that 39% of all adults go away with their parents or in-laws. One in ten kids admitted that a free holiday was the main reason for going away with your parents but half said it was to spend more time with them.
