Arguing between holidaying couples starts even before the trip begins, according to a poll.
More than half (52 per cent) of couples cannot agree on a destination, while 37 per cent fall out over the frustrations of the booking process, the poll by travel agent ebookers.com found.
Once away, two-thirds of couples end up arguing, with 25 per cent having rows by the third day of their break.
Topping the list of trigger factors are how much time to spend together, and money.
Women are most likely to blame alcohol for fuelling rows while away, while men get annoyed if their partner eyes up others on the beach.
Despite the disagreements, 56 per cent of couples said they had come back from holiday feeling their relationship was stronger.
The poll of 2,000 adults also showed that beach breaks are most popular for those wanting a romantic time away.
As many as 22 per cent of those questioned said they had yet to find a holiday destination in Europe that offered everything they needed.
Ebookers UK marketing manager Jessica Craker said: “Holidays are a great excuse to spend quality time with your loved one and should be a wonderful experience, so it’s a shame some people aren’t getting the most out of them.”
