Fr. You do not indicate where in the world you are located. If you did, we might be able to link you up with one or more forum veterans to provide direct advice and recommendations.
You might even get lucky and score one of our camino 'addicts' who would be willing to accompany your group. Having someone along, who knows the proverbial ropes, is a big help. You are leading the pilgrimage, they are your local scout...
As you plan this, if you want, or may be asked to say Mass daily or frequently while on Camino, the easiest way is to ask the locals to borrow the local, likely locked church.
Though a layperson (I have the honor to be a lay-brother / cofrere in the Archconfraternity of the Glorious Apostle Santiago) in my observation, there is usually a small group, typically of older women, who continue to maintain and keep clean the inside of most closed churches along the Camino routes. Typically, they get together daily to recite the Rosary in the church, usually at about 7:30 pm, before an 8:00 pm Mass if they have a priest, like you.
If you get lucky, you might be able to piggy-back on this already gathered crowd to offer the Mass, just after the Rosary is recited, in Spanish...same prayers, different lingua franca.
To find out how to do this, I have seen instances where the bar / cafe closest to the church will know who has the key, and can make the phone call(s) for you. You, or someone else needs to speak Spanish well enough to make this request known.
Coordinate a Mass time 7:00 and 8:00 pm are popular. After the Daily Rosary works best. Then make certain that everyone knows they, and anyone else they can tell, is warmly welcome to attend. If the Mass will be part Spanish and part English, tell them this. Just having a live priest come to serve Mass is a really big deal in many of these smaller villages.
Assuming this works, you will achieve instant rock-star status. About the only thing better is to offer the full Mass in Spanish. However, you know where - at home- to obtain a copy of the Ordinary of the Mass in English/ Spanish. Practice makes perfecto...
To learn or polish your extant Spanish, I recommend
www.duolingo.com as it is free. I have been using it daily for one-hour for at least 730 days, as of this afternoon.
Even if you just do the opening greetings, Penitential Act (or just use the Kyrie), Gloria, and Our Father in Spanish, plus the Creed. The Kyrie is fine in the original Greek, the Angus Dei is fine in Latin. Trust me, the Spanish know it.
BTW, and just a tip, homilies usually always relate to the Camino. As the Camino is an apt metaphor for life, this is usually not a problem. If you get lucky, the day's readings or Gospel might inspire you. But, do keep it short(ish) people are likely hungry and thirsty.
In Spain and in my experience, they use the shorter Apostles Creed, rather than the longer Nicene Creed. If you can do this in Spanish, that would be HUGE. You can say the rest of the Consecration prayers in silence or softly.
Finally on this point, my sense is that the ladies group in one village will know the ladies running the similar group, down the route. It MIGHT be possible to create a chain effect, where the folks you said Mass for tonight could call down the road to make arrangements for using the next available church. If you do not ask, the answer will always be 'no.'
This could also be helpful to arrange down the road lodging for a group. Out on the Camino, everyone knows everyone else. They cover each other and help one another. This could work to your benefit. If you have a good result at Village "A" with a Mass, offer to do it again at your next, stop, etc.
Add that you need to line up appropriate housing for your pilgrim group, if that might be possible, like to call ahead to a hostal or pension, etc...
Do not be surprised if the locals end up opening up their private homes to take you in. If this should happen, consider it like a donativo albergue and please leave a generous appropriate donation, a plain envelope would be nice, or wrapped in a sheet of paper. Allow these people to save face by not handing over cash. They might be offended. You DO NOT want to offend a Spaniard.
If there are supplies of wine and unconsecrated hosts, the ladies caring for the church will know where to find them, as well as the sacred vessels needed. Likewise if there are vestments for visiting priests. All you need to bring to the "party" is:
- Your ordained Catholic priest ID card.
- Your stole
- Your mini - for when I say Mass just for me - kit
- Some Spanish capability
Trust me, every village where this is possible will love it.
I hope this helps move the ball down the field / pitch a little.
), yoga, dancing, etc etc, can all contribute.
