We walked the Portugués last year in late March. We had no problem hooking into wifi wherever we were from albergues to cafes along The Way. Perhaps it was because we were ahead of the crowd walking that early, but we didn’t find albergues offering pilgrim meals as I found on the Francés. However, there were plenty of restaurants offering a multi-course pilgrim’s meal. But with all the great seafood available, it was hard not to seek out restaurants offering pulpo or bacalhau.
Regarding the cobblestones, although I had no difficulty with them, my wife developed knee problems after five days on this uneven surface. When we reached Tui, we used a luggage transport service (Tuitrans) to ship her backpack ahead for a couple of days so as to make walking easier. Although we travel light with little more than a 6 kg pack, the stones still caused some problems. Bom Caminho!
