The ENTIRE issue with the new Compostela process is EDUCATION. Once most or all pilgrims understand they can submit data in advance, show their QR code, and speed up the entire process, for everyone, the entire process will accelerate.
Those of us who have worked with this new process are praying that the word gets out and people participate in advance submission of their data before the 2022 season starts.
Absent this, it is not possible to hire enough staff or engage enough volunteers to process the numbers of pilgrims anticipated for 2022. Only automating as much of the process as possible will ameliorate long lines and frustrated pilgrims.
The final point in this regard is that all pilgrims must plan enough time at Santiago to allow for at least one night at Santiago, preferably two, in case you are shut out of the Compostela process on your arrival day and are told to come back tomorrow. It happened a lot this year (2021).
Far too many pilgrims arrived thinking they could stroll in, get their Compostela, attend the noon pilgrim Mass, and catch a bus, train or plane out of Santiago later the same day. It has not been like this for several years. The COVID pandemic made it worse, with reduced staff and office hours. All the folks responsible for the Pilgrim Office are concerned about the 2022 season. With the Holy Year (with availability of the Jubilee Indulgence) extended another year by Papal Bull, until the end of 2022 liturgical year, the pent up demand across the world is going to hit as soon as it is safe to come out and do Camino.
Original estimates for the 2021 Holy Year before the COVID pandemic ranged from 650,000 to 700,000 pilgrim arrivals. The 2019 total was about 349,000. The 2021 arrival total will likely be about half of the 2019 number. All the COVID pandemic did was delay the inevitable surge of pilgrim arrivals from 2021 into 2022.
Be prepared! Plan for two nights in Santiago. Do not wait until you arrive to make reservations. During 2022, finding a bed is going to be difficult, especially during the peak season - May to September. Please plan ahead and early.
Hope this helps.
