Hi,
Everyone does their own Camino, their own way - there is no right or wrong way, so these are simply my own thoughts...
We did the whole
Camino Frances from SJPdP in September in 2014 and 2015 and I will go alone this year and Ce next year (2017) in April - becoming Camino tragics!
September was a good time as we were coming off the back of the busy period and Pilgrims were less in numbers. By the end of September some Albergues were starting to close for the off season.
I don't like to book ahead for Albergues (many won't let you - except for Orisson - if you stay there, booking is a must) as I don't like to be on a timetable and under restrictions as I listen to my poor old body and try to walk the whole way carrying my pack.
The uncertainty of getting a nightly bed adds to the experience for me as it forces me out of my normal comfort zone and provides many wonderful experiences.
I do worry about walking on if there is no room so I am comfortable most days walking about 20 Kms. This allows me to book in at an Albergue just as many open, soon after midday.
Finally, many pilgrims seem to use the
Brierly Guide and if you don't struggle to reach the top of each page, the Albergues seem less full.
Also I think more people start off at a weekend so waves might be going through and it helps not to be on the crest.
This forum has a great resource that shows pilgrim nos by days by towns.
