The issue of accommodation is definitively one of the most worrisome when it boils down to traveling. The Couchsurfing Project aims to do its best to alleviate such worries, and to connect people and spread tolerance in the process, as well as promoting cultural understanding. The main objective of this site is not just to modify the way people travel, but the way they relate to each other and connect with the world at large. The basic premise of couchsurfingrevolves around opening your home to travelers and provide them with accommodation; or become one such traveler and find accommodation at someone else’s abode. Couchsurfing is free to join and use, and there are safety guidelines both for surfers and hosts. In addition to that, there are guides to couchsurfing, tips for ecological traveling, advice for gay and lesbian travelers, advice for family couchsurfing, and all the information one may need in order to become a good guest or host. A nice touch is as emergency list that lets members help each other in cases of emergency.
