The Science Behind the Booking: New Formula Unlocks Key to 'The Perfect Holiday' PR Newswire DENHAM, England, July 11, 2012 DENHAM, England, July 11, 2012 /PRNewswire/ -- - Travelling for no more than four hours is the key to a perfect break - Edinburgh is the UK's no. 1 Staycation Destination This summer is set to be the biggest season of staycations with 30% Brits predicted to book a holiday in the UK*. But according to a new scientific study, it's not the recession and summer of sport keeping holidaymakers in the UK in 2012. The study commissioned by Holiday Inn has identified the formula for The Perfect Holiday - three days long, and no longer than four hours from the front door - helping to ease the stresses and strains of time off work and travel. The Perfect Holiday was identified by a top UK research agency who looked at the trade-off between the monetary expense of the break vs the benefits of the holiday whilst taking into account factors such as cost, days and the amount of time required off work. Other considerations include levels of anxiety and boredom at the airport and relaxation benefit of being away from work. Expert psychologist Dr David Lewis said: "Research shows that many people find breaks abroad so stressful that they return home more worn out than perked up! This helps explain the growing popularity of shorter breaks away in the UK, with many holidaymakers finding that taking several long weekend breaks is more relaxing and rewarding.
