That is one sweet route! If you're going b&b/hotel only i'd not worry too much. They are everywhere in that region. How many days are you taking out for this? If got say a week you can take it easy and have maximum enjoyment of the views and scenery. This time of year I do advise you to bring all warm cycling clothes, good overshoes and at least 2 pair of merino socks. A nice set of off-the-bike shoes is also recommended as it may be too cold to go around in flip-flops.
