Less busy was one of the reasons why I did the Ingles, plus you can walk the whole route, which gives a greater sense of achievement. Because the Ingles is less busy, then I do not think there is the need to stay in places which are not at the end of a stage in guidebooks, as with the Frances.
Definitely stay for the evening / night, and labour in both Pontedeume and Betanzos - they are real highlights of the trip. As I keep saying, the 28 km to Meson de Vento or 33 km to Buscas from Betanzos are not as bad as you think on the route, because the killer hill after Bar Julia is no longer there.
I walked 1.5 hours further than Hospital de Bruma down to Buscas to Casa Rural Donamaria, which was 9 hours from Betanzos (the extra 1.5 hours was mainly on a flat country road). Casa Rural Donamaria was the best place I stayed en route - a lovely fresh home cooked fish evening meal made by the proprietors at an hour of my choice, so it was worth the extra 1.5 hours slog to reach from Hospital de Bruma, and it also made the next day to Sigueiro a short 6 hour walk, with an even shorter walk the next day to Santiago. Lovely garden at the back of the Donamaria, I can imagine resting on a summer's evening or morning for a while.
9 hours walking is 8am till 5pm (and this included stops for snacks and lunch), just walking at a steady pace, although I confess I was not doing this in the heat of the summer. If you look after your legs and feet, you will be surprised how far you can walk on the Camino, especially after a few days, when there is nothing else to do, and reaching your sleeping point depends upon it.
Consider also transporting your luggage each day by the postal service, Correos, so that you only need to walk with a day rucksack with provisions. It can be done online, in English, does not cost much and is reliable, and makes a huge difference.
