It's a great way to travel and because the accommodation is free you can travel longer. You will connect with people in their communities on a completely different level than that of a tourist.
We spent six months touring Europe staying with people and enjoyed over 100 nights of accommodation for free. More importantly our lives were enriched by meeting these people and finding out about their way of life, exploring their country and meeting their family and friends.
The people we met included; a helicopter mechanic in the army, a gastroenterologist ( a young guy with loads of energy), an architect, a nurse, teachers, several families, backpackers, artists, students and the list goes on, but all really interesting and welcoming people.
When planning our holiday in Europe I searched for ways to obtain budget accommodation and found several sites, but was a little uneasy about how it worked. Anyway we checked it out and found some great genuine people – but we did our research. The biggest site was Couchsurfing.org and this has over 1.5 million members and many groups that you can choose to belong. The site is easy to navigate and all you need to do is develop a profile about yourself. I would advise people to spend time on this as it helps your case of being hosted.
There are many other schemes where you can obtain free accommodation for your holidays, which includes accommodation for families and your dog if you want! Also if you have a van that you sleep in there are places where you can park. I have included these on my website www.free-accommodation-for-world-travel.com so check it out.
