My husband and I walked in the fall of 2015. We booked one or two days ahead through bookings.com or sometimes the owner of the Casa Rural would recommend a place and call ahead for us. When you set up a firm itinerary with a company, you have to arrive at the next place no matter what.
We used Jacotrans for luggage transport. There are envelopes at all the accommodations, you fill out you information, put the name and address of your next place and put the money in the envelope. We shared a duffel bag and carried small day packs so we only paid for one bag. It was 5 Euros. Your hotel will call them, they come pick up your bag and deliver it to the next place.
The Camino is really easy to manage on your own. The Spanish people are very helpful.
There are many Facebook groups, one is called the American Pilgrims on the Camino, people are very happy to give advice.
