I will keep up with vaccination requirements and boosters as available, follow masking protocols, use hand sanitizer, and eat outdoors when outdoor seating is available and weather permits. That is essentially what I did last year when I went. I have eaten in crowded restaurants at home now - so will not be afraid to do so in Spain.
Social distancing will be part of my plan with locals (out of respect for their health) and probably most pilgrims that I don't become close friends with. However, last year there were about 30 of us walking the same stages and we became an extended Camino family. We were alway in and out of each others orbits, sharing rooms, sharing meals, and walking together sometimes. This summer will be harder. First of all - last summer I knew exactly who was vaccinated and who wasn't (most of us were) and while vaccinated folks can still get COVID and spread COVID - there was some degree of comfort knowing that most of us would not get very ill from COVID. This year there will be many more pilgrims and vaccination status is likely not to be as big of a topic of conversation (last year it was because Spain had just opened to us vaccinated folks). It will be interesting to see what kind of Camino families form this year. I certainly wouldn't expect to know and interact with everyone if it is much more crowded as I am expecting it to be.
As for the albergues - blankets were usually not offered, kitchens were usually closed, communal meals were often not happening and beds were at half capacity, MANY albergues were closed, as were many bars. It was hard to find early morning breakfast if you didn't eat at your albergue - so I found myself needing to stop at more grocery stores (and buy foods not requiring cooking). This year I would expect it to be a lot busier and perhaps I may see less of these issues - but still planning in case this is still the case. Especially the need to carry some snacks for early morning (I have a hard time eating as soon as I wake up - so often skip albergue breakfasts).
Overall though - not stressing about COVID at all. As long as some deadlier variant doesn't emerge anyway.
