I detect a bit of a clashing of cultures here
, between those who come from areas where discounts in the hospitality sector (and in general) are more common than in others, between those who have walked and those still to walk, between the albergue fans and the hotel/pension aficionados, between The
Camino de Santiago and the Camino del Norte, those from far away and those living near-by. Someone mentioned the "camerero" rate. And Booking.com.
In my very limited experience - and without having ever asked for a pilgrim rate or any other discount or freebie - I was told on two occasions at check-in or check-out when I had booked through Booking.com: 1. that it is a pity that I had booked through Booking.com because they cannot now give me a lower rate although they would like to offer it to me (I was wearing standard pilgrim gear) and 2. when I come next time I should book directly through the hotel and ask for the pilgrims rate (which is the same as the business travelers rate) because they don't offer this rate through Booking.com and that they have to pay a commission to Booking.com for every booking.
In a third case (on the
Camino Frances) where I talked with the owner for a bit, it was clear that the small hotel was also aiming to attract customers who stay longer than just the one night a pilgrim stays. Which is mostly likely often the case in the area of the Norte, which does not cater primarily for the pilgrimage sector and to which the initial question refers?
