See, I told you the forum would help you...
The bottom line appears to be to save your money. This is not intended as an editorial against this or any other preparatory class. Do your research here. Learn everything you can. We are all here to try to help - as you can already see. Perhaps, try to read a few books written by Pilgrims. Then, use any money saved to gear-up or while on your Camino.
As you live "down under," visit
https://www.amazon.com.au/?tag=casaivar02-20 and search for "
Camino de Santiago." I think you will find just about everything there.
Many of the books are also available in Kindle format. So, as you will read often hear, these books "weigh practically nothing... ROFLMAO..." The joke is that a lot of "it weighs practically nothing" eventually ends up weighing 10 kilos or more.
It is like the old adage coined by the American philosopher/politician/inventor, Benjamin Franklin: "save your pennies and pretty soon you will have dollars..." This basic phrase has been purloined often since. But in the Camino incarnation it means that add a gram here and a gram there, and pretty soon you are carrying extra kilos of deadweight. I do speak from first-hand experience in this.
However, in this age of electronic books, the adage is not true. So, once you make the basic decision to bring your Smart Phone or Kindle, the electronic books, do in fact weigh nothing.
Yes, you can buy a Spanish SIM card, micro-SIM or Nano-SIM for your phone in Spain to save a lot on overseas costs. Use the search feature at the top of the page to check the Forum for more on "mobile phones."
If you do not have a Kindle reader, the Apple iTunes App store has the free iPhone / iPod / iPad app from Kindle to be able to read Kindle books on your iPhone / iPod or iPad. One presumes the same sort of app exists for Android powered Smart Phones.
One of the better books (IMHO), that many people (including moi) have read is written by SYates, of Forum fame...see the thread above. I believe the title is in her signature. You can even send her a message to ask about it. I am sure she would reply. I do - always. She is a very experienced pilgrim who writes simply and provides a wealth of information. I recommend the electronic Kindle edition. One other book you might consider is "
Camino de Santiago - Practical Preparation and Background " by Gerald Kelly. I believe it is only available as a Kindle download. I found both books very good, even if I did read them AFTER my first Camino.
I hope this helps.
