Britons unable to switch off on holiday In a poll of Britons in management roles, carried out by the travel agent Sunshine.co.uk, 49 per cent said they looked at their account "on a daily basis" during their most recent holiday. Nearly three quarters of those who admitted doing said they were with their partner and their children during the break, and 44 per cent said that the regular checking of emails had caused friction. Around a quarter of those questioned said they actually did work during their last holiday. The study also revealed the professions which find it most difficult to switch off from work commitments - they included PR/marketing, sales, media and legal. Interestingly, considering that a large number of hotels continue to charge guests for internet access, it was also found that 86 per cent of Britons check the Wi-Fi availability in their accommodation before booking. Meanwhile, the results of a survey by TravelSupermarket, published last week, revealed that the average Briton takes five gadgets with them on holiday. Digital cameras, taken by 88 per cent of travellers, smartphones (86 per cent) and eReaders (77 per cent) were the items most commonly taken overseas. Earlier this month Sarfraz Manzoor visited a private island in the Grenadines for Telegraph Travel to enjoy a technology-free holiday. Click here to read his account of the trip.
