It seems we just cannot switch off on holiday as a new survey says 90% of us lose two days of vacation using our tech devices.

The lastminute.com study from the UK shows almost half of travellers rely on their devices to keep themselves occupied while over a quarter refuse to stay at a hotel that does not offer free wi-fi.

And more than 1-in-10 of us actually buy a foreign SIM-card while on holiday to access the internet.

The lure of social media is also gripping with 31 percent of holiday-makers posting real-time updates for their friends and family.

The survey says the facility for immediate sharing provided by technology has replaced the traditional holiday postcard and has made the 'selfie' king. 28% of holidaymakers are taking snaps of themselves and uploading them on social media.

It says women are the biggest 'selfie' sharers, with nearly 30% using their kit to take pictures of themselves on holiday while 25% men admit to taking self-portraits for photo sharing sites.

Mark Maddock is Managing Director of lastminute.com UK and Ireland.

"Whether it is a good distraction or not, the reality is our customers are now always connected - and they want this to continue seamlessly when they are abroad. We are finding with our hotel partners it is no longer enough to offer guests free wi-fi, it is also about the quality and speed of the internet connection" he said/

"We have connected travel with technology since 1998 but would be the first to say to customers - don't forget to switch off when you are on holiday and open your eyes to where you are in the world" he added.
