No worries about having people around you in March.
Not so many students and young people because they will be in school, but a lovely cross section of mature pilgrims from all over the world.
You will meet new people every day, and in a day or two will form a loose group with 6 or 10 pilgrims who happen to be walking the same stage each day. People will join the group, and others will drop off as you go along.
Buen Camino.
