Hello @
dustylee
The first question is about where you want to start. Are you going from Lisbon, or from Porto, and how many days do you have to do the Caminho?
The second thing is that getting that service here in Portugal will be very, but very expensive. And then you have another problem, which is that probably most of the national transportations companies, won't take the service over the border. So imagine that in one day, you have to start in Valença do Minho. You would still to walk 5km to other side of the border and arrange a meeting with the company (this is a supposition, probably you will find a company that could go out from the border, but once again, they will charge extra, and you some sort said that you have a low budget to fulfill).
I'm with the opinion from my good friend @
Albertinho that you should take your backpacks with you. For the Caminho Português, 7 to 9kg it's ok. And his advice about anti-blister ways work (I also use them
).
If you still intend to have a service to carry your backpacks, you could also do it in another way. When you reach Portugal, why don't one of you rent a car with a big luggage and go has a support vehicle? Its better, and probably cheaper, just don’t forget to warn the Rent-a-Car company that you will get out from Portugal with the car, so that they can put the international insurance to work.
And last, but not least, don't forget that if you use a support vehicle, probably you will be the last ones to have access to the Albergue. You are in the bottom part of the priorities. And they control that very well on the Caminho Português.
Best Regards
Diogo
