HOW long would you wait before going on holiday with your new partner?
Well, according to a new study, modern couples head off on a "make or break" holiday after just 12 weeks.
A survey of 2,000 adults found 25 per cent of couples take a trip three months or earlier into their relationship.
And around one in five go on a beach break - specifically to test if their partner is worth sticking with for good.
A seven-day break to a short-haul destination is the most common, while one in eight confident couples jet off for a fortnight.
One in 10 decided to travel further afield together, while 50 per cent chose somewhere closer to home.
The study also found couples' behaviours are different on holiday, too.
Three in 10 will have more sex, with two in five listing holiday sex as a way to feel closer to their other half.
A third of couples believe that their partner is also more romantic on holiday.
Of these, 56 per cent think their partner brings those feelings back home, while 25 percent believe the romantic feelings remain for two weeks post-holiday.
And it seems huge life decisions are made on getaways too.
A third of those surveyed used their holiday as an opportunity to talk to their other half about future plans, with one in eight couples deciding to get engaged or married.
One in 10 decided to move in together.
And a further 10 per cent felt inspired to start a family whilst on holiday.
According to the survey, older couples, aged 55 and over, are the most likely to have a harmonious holiday together, with 43 per cent saying they can’t think of anything they disagree about with their partner.
However, older couples who do fall out are most likely to disagree over directions and what to pack for the trip, while younger couples argue over money and which activities to do.
Younger couples surveyed place more importance on holiday sex and taking lots of photos together in order to feel closer to their partner on their getaway.
Older couples consider escaping somewhere idyllic with their partner and getting away from the daily grind of chores as main reasons they feel closer to their other half on holiday.
Karl Thompson, managing director for Sandals Resorts in the UK, which commissioned the study, said: “Whether it’s a couple’s first trip together, a honeymoon to celebrate, or a more traditional break away from everyday life, a getaway with your partner can be the perfect chance to spend quality time together and strengthen those romantic bonds.
“Whilst a week-long holiday may seem lengthy for a first trip away, it can be a good opportunity to see if a new relationship will stand the test of time and whether any romance lasts when you get home.
“It is easy to place a great deal of expectation on a holiday with your partner, but they can be a great time to shake up a relationship and make plans for the future.
“Despite worries about holidays going without a hitch, couples are still finding time to use their breaks away to plan the next step in their relationship and set life-changing decisions in motion.”
