Hotel for the Picos part of the stay now confirmed - details in the original post on this thread.
We've had to move further west in the Picos than originally planned due to difficulties getting suitable hotels for our group.
As per the update on the original post, all spaces are currently allocated. If someone is seriously interested in joining the trip then please PM me to discuss, and I will go back to the ferry company and the hotels to see about adding more to our booking.
