I voted 'been there, done that' and 'no'. That is my story in a nutshell.
It was 2017 and I was walking on the Camino del Norte. I had walked for about 2,5 weeks and for some reason I was losing the spirit to move on. As I didn't really know what to do I walked on for another day and arrived in albergue El Reposo del Andayón in Cuerres (doesn't exist anymore).
It was a donativo albergue that had opened only a couple of weeks ago. At dinner the owner told us that she considered working with hospitaleros. I saw it as a sign and as a 'the Camino provides', so after dinner I asked her if I could stay and work as a hospitalera. The next morning I was serving breakfast to my fellow pilgrims.
I stayed for another 2,5 weeks and then gave up. It was exhausting. Not the work itself, but to be around people almost all the time. I happened to be a much bigger introvert than I thought I was.
I had a full schedule 7 days a week: getting up at 6.45am to prepare breakfast, waking up pilgrims, serving breakfast, trying to get everyone out of the door by 9.00am and then cleaning and making the beds until 12.00am. Then I got my holy hours of free time. If it wasn't raining I went out with the dog or walked to the closest beach.
I had to be back at 3.00pm to receive pilgrims, registrate them, show them around, explain them the (many) rules and from then on I just had to be present. Around 6.00pm I would start helping cooking and we would have dinner at 8.00pm. After dinner I would clean up before I could retire to my room around 10.30pm. I then still had to listen to the chatting of my roommate, a friend of the owner who didn't stop complaining about her.
It wore me out to a point that I locked myself up in the bathroom to read a book. So, yes been there, done that, learned a lot about myself and no, wouldn't do it again. Well, at least not under the same circumstances.
