How did it all turn out?
Were lots of people turned away?
According to information from the volunteer group that provides most of the hospitaleros for Roncesvalles throughout the year:
The Roncesvalles albergue had beds available for 257 persons throughout the time of operation, ie March to October (183+34+40=257), not just 183 beds as often claimed here. During winter, the Roncesvalles albergue is open but with a reduced number of beds and no volunteers, it is then run by the staff employed by the collegiate church.
On Good Friday they accommodated 322 pilgrims (the "camp" was still open at the time but was soon to be closed).
First of May long weekend: Pilgrims were regularly sent away. Friday 28/4 and Wednesday 3/5 were the busiest days when SJPdP announced that 400 persons daily were on their way. Roncesvalles albergue organized taxis for those they could not accommodate.
May in general: Roncesvalles albergue was regularly full and pilgrims had to be sent away, for example 40 persons on Saturday 20 May.
First week of September: every day full house and 40-80 pilgrims were sent away nearly every day. Taxis with capacity of 8 passengers constantly coming and going.
Once, a pilgrim presented a letter from his bishop that said that he can sleep in the church but Roncesvalles did not allow him to do so. They did find him a bed, however.
As a matter of policy, only about 60 to 70 albergue beds can be reserved in advance, the rest is first come first served.
