There's a lot to be said for lounging around
The travel trend of spending a night on a stranger's couch for free has exploded in popularity across Asia, particularly in mainland China.
In Beijing and Shanghai, the number of people willing to welcome people on off the road is taking off, according to a US-based website that links hosts with intrepid travellers.
The phenomenon, known as 'couchsurfing', is particularly popular with backpackers and is made possible through Couchsurfing.org, which was founded in 2003 and now has more than four million members.
Casey Fenton, a 34-year-old American who came up with the idea when he was a backpacker, says Asia is one of the fastest-growing regions.
Five years ago, Couchsurfing.org had just 2,000 members from mainland China, Fenton said from the site's headquarters in San Francisco.
This figure jumped to 37,000 by 2010, and last year the mainland had 60,000 members.
