Oh, and touring without booking ahead - it depends on where you're going and what your tolerance is for staying in chain hotels on the ringroad. When we did our big ride through France (link below) we realised that we'd have to book ahead to stay on the route we wanted, because in deepest darkest France there are relatively few hotels. Plenty in the cities and large towns, and particularly plenty of Campaniles and Ibises - but they tend to be built on cheap land convenient for cars. Which often isn't so convenient for a cyclist.
