But if Deba to Markina is the worst bit and is only 21km, then I think it would be completely doable.
Mikevasey...were those double ensuite rooms 15euros per person or for the room? (I'm guessing the former!)
Some places were holiday apartments on my 1st camino, were there was a sliding scale of costs depending on how many people stayed, I was the only person in one in Muros de Nalon and paid 30 euros if another person came I would have got 10 euro back and we would have paid 20 euro each and there was bed 3 more beds in the quite sizable apartment so I it may have gone down per person quite a bit more.
Another option for you is camp sites and there is quite a few along the northern route, a lot have static tents which can be rented out per day and could quite easily house 8-10 people. What I noticed was some sites I stopped to eat and drink in June of this year looked very empty in comparison to July 2010, so if you show your credencials and walk out of season you may be able to get discounts.
Distances will be a problem, I was trying to remember what would be problem areas for you, I would have to add Santona to Guemes 26km but I did not walk the coastal way so there may be options on that route for you, I headed inland and took my own way. Deba(gijon albergue) to Aviles, there is 31km gap here, I would walk into Gijon train staion(6km) which is quite a nice walk from Deba as long as you follow the canal to the sea once you get to Sporting Gijons ground, from the train station take a train to Aviles, this will miss out quite dangerous road walking and long stretches next to Industrial complexes, you may be able to head out to a possible new albergue in Raices Viejo which if it opens is 4km after Aviles. Soto de Luina to Cavedeo, by the road route is 25km with only a 10 bed albergue at the end however there is a lot of campsites and other accommodation there. If you walk the high route it is only 18km, quite tough but very beautiful, read MikeIans blog for their description of Cudillero to Cavadeo. After Luarca there is a route called Costa Naveiga, look for it on wikiloc, which used to be on the camino, but I think they changed it when they opened the albergue in Pinera and took the route inland over more asphalt, so that is a beautiful 'off' camino way to look for, albergues are quite frequent after Luarca with the exception being Miraz to Sabrado dox Monxes, about 24km, but this is quite a gentle stage. Another suggestion is that from Colombres take the train 2-3 stops on and miss out some really bad road walking, the start of the E9 coastal route is about 8km after it and is a treat for you and your kids.
Sorry I couldnt give you more details about accommodation but I have had to email friends who walked as couples, so I will see what responces I get from them.
