The BBC looks at the growing trend of people swapping homes to cut holiday costs.

Would you swap homes with a stranger in exchange for a cheaper holiday? Or would the idea of someone sleeping in your bed and using your kitchen while you were away put you off? Henry Vanderpump, 42, his wife Elliw, 39, and their two young children have had two home exchange holidays in the past two years and have another planned this summer. In each case, they have stayed in another family's home, while that family stays in theirs, a five-bedroom house in Tarporley, rural Cheshire. Neither side pays anything for their accommodation, although they do pay an annual membership fee to Home Link, the listings site they use to book the trips. So far, the Vanderpumps have stayed in similarly sized properties in Hamburg and Copenhagen, and Henry says they have saved around £2,500 on accommodation per trip, plus a further £700 on transport, as they also swapped cars. "We used to have one holiday a summer, now we have two [because of the savings we make from home exchanges]. And the kids love the idea of living in someone else's house while that person is living in theirs." Home exchanges have been around since at least the 1950s, but an increasing number of people seem to be embracing them because of the rising cost of living, or simply to experience a new type of travel, commentators say. Henry says the best thing about swapping homes isn't the savings but getting to visit places off the tourist trail and have a "really authentic experience".
