Yes - I signed up to Warm Showers last summer. I live on a remote Welsh farm - and still have had three separate sets of travellers cycling in here. I have thus far enjoyed the involvement immensely. You just have to be completely straight on both sides about what you each expect from the first point of contact. Let each other know the constraints to do with ' notice period '. I'm fine, for example, with saying I need, for example, 5 days notice, and if the visitor can't give that, they need to be prepared for me not to be able to host them. I felt really happy to be able to offer a French family of 5 - three small children included - a hot shower and a good hot meal on the most windy and wet midsummer's day I can recall! (But thats Wales for you!)
