Yes, I probably was thinking too much. But the reason which made me think was their response to my enquiry. I only asked if they service through the year. In their response they emphasized prebooked accom. with the reception hours 8-15, and listed a kind of accom. they don't deliver, ' In B&B , Private Apartments, Airbnb, public albergues...' Why B&B??? I still don't know.
However, encouraged by the responses of the members with the experience on the ground, I went ahead and booked all accom. now. While only one responded to my Q before I booked, they said OK after I booked and sent another Q in English and Spanish. I paid extra for free canx as I didn't know the answer in advance. I avoided the places I already knew they don't take delivery, incl the one which said they accept luggage transfer 8-12. That wasn't good enough. The member's photo of the lone rucksack in the post..that was at a municipal albergue!
Thank you for the advices, everyone. Without them I might have resigned to carry my backpack.
