I'm looking at a guide right now that shows sufficient choice in places to stop, and there are places to stay, and to eat. Maybe not huge choice, but enough. I can't see needing anything more. But then I'm OK about sleeping in a polideportiveo or even under a church porch (which I've admittedly never had to do).
I for one hope it does not get commercialized. Right now local people are still happy to see pilgrims...how long has it been since that happened on the Frances (or even the Portugues)?
There are plenty of places to stay, but not too many albergues. As far as places to eat are concerned, there are some excellent (and cheap) restaurants, where many of us have eaten time after time and will heartil recommend.
The only real problem is with a couple of the longer stages, where there are few places to stop off for refreshments.
A Rúa to Quiroga is one such stage, but you have my suggested alternative (in the guide) of walking on from A Rúa to Montefurado the day before, then getting the train back to A Rúa, and doing the opposite journey on the following day: train from A Rúa to Montefurado, then continuing on foot. The only place open is the summer-only chiringuito by the river in Soldón.
If you walk all the way from Monforte de Lemos to Chantada there is nowhere to stop for a coffee, soft drink or beer until Belesar. The alternative, followed by others on here, is to carry on past Monforte and stay the night in one of the casas rurales or in Escairón. This cuts the next day's walking down considerably.
I'm pretty sure that I know every single watering hole, hostal, pensión and hotel between Ponferrada and Santiago! If you need any help, please drop me a line!
Shhhhhhhh....
