My view would be that you shouldn't have interfered with someone else's sleep, no matter how disruptive it might have been to people who were clearly not prepared for sleeping in a pilgrim dormitory. Leave any disruption to a partner or spouse. The onus is on individual pilgrims to be prepared, and that means having the sense to bring along earplugs if one is going to sleep in a dormitory.
I know I snore, and I was prepared to admit it last year until I was asked one night to sleep in the common room rather than the dormitory. I was reluctant to do so, but agreed. As a result:
- I couldn't go to bed until the last of the others left the common room, which some did with bad grace because they wanted to avoid the 'lights out' in the dormitory
- Every half hour or so, or so it seemed, someone would go to the toilet, and turn on all the common room lights because they were on the same switch panel as the toilet lights
- then to top it off, the person who had asked me to sleep in the common room was up at 5am noisily packing their backpack to leave at the foot of my mattress with all the lights on
- All of which resulted in one of the worst days that I had on the Camino the following day.
To top all that off, I was informed a couple of days later that there had been several snorers in the dormitory that night, despite the faithful pledges they had all made to the hospitalera that none of them snored.
My lesson. Don't offer the information, don't shift out of the dormitory, and if someone asks point out politely that you won't be the only snorer, and it was their responsibility to come prepared to sleep in a dormitory.
