Last year my motorbike holiday was a tour of Italy, likewise no booked accomodation. We went down the west coast about 100 mile beyond the Amalfi coast (which is a beautiful stretch of coastline, but was horrendous in the traffic and June heat) then across the country to the East coast which had less traffic but fewer nice towns. In summary, a beautiful country spoilt by awful traffic anywhere near a large town or city, probably better in an air conditioned / convertible car than on a bike. Many years since I went the lakes but despite the journey to and from it is lovely.
