Just a followup, since I´m now trying to find places to stay for the 9 nights before I arrive in Montserrat, which is where LT and I will join up, and also where the albergues begin! There are a couple of albergues between Llanca and Montserrat, but they are youth hostels, and I don´t wish to sound ungrateful or snobby, but I have decided that in my 65th year I am going to stop sleeping in youth hostels (with an exception for the Camino de Invierno).
I have been surprised to find some pretty cheap options on booking.com. My first night in Llanca, in fact, in the Hostal Llanca, is 24€, which is the price the albergue juvenil was quoting for a room with a bunch of bunks.
There will be a couple of expensive nights. Vic about 45€, and then maybe L'Estany in the monastery, but the others that I´m coming up with are all in the 20s.
So -- many thanks, Kinky for suggesting Llanca. I have found a gps track from Llanca to the monastery at San Pere de Rodas, which is the "not to be missed" first attraction on this Camino. Since I´m walking a "false camino," I suppose there´s no reason to start in the "false starting place" of Port de la Selva; might as well start in Llanca if I´m going to be a fraud anyway.
