I'm back
Despite coronavirus and everything it wasn't so easy to find accomodations day by day as I hoped.
Many were already fully booked the day before, some had vacancies but were too distant or too close.
Towns are small, once you got as far as you want you may find yourself in a place that only have a couple of options and it's not nice to find out it's fully booked or out of budget.
I felt like I had to book 1 day in advance and so I did.
YMMV
