RayStay.com is a free service connecting travelers looking for accommodation, with the people who want to host them. Even if you don't have a spare room, you can rent out your couch or a futon or pitch a tent in the backyard - just price it appropriately and let the extra cash roll in. This site provides a place for travelers not only to find a place to crash when their on vacation but also to get a better sense of the place their visiting by interacting with the locals that provide accommodation. Those posting their place for accommodation can choose who you’d like to stay over, and of course set the price to whatever they think is appropriate. The price mechanism creates a better market for accommodation listings. It's better than putting an ad up on a classifieds site such as Craigslist because it's a little less anonymous and the listings stay up until a host takes it down instead of being pushed down by new ads everyday, and the best part is that it's completely free.
