Driving from uk to Camposol

Hi All

Looking at driving from uk to Camposol

We will be bringing our dog with us 

We’re aiming to travel via the euro tunnel , through France , following the route past Rouen , Toures  , le man’s on to San Sebastián and then down through Spain past Huesa and zaragosa

if anyone has driven This route if you could give any pointers around tolls and if you stayed at any of the hotels in the route and especially if dog friendly 

any tips or hints most welcome

we’ve costed the trip and looked in to the insurance , and breakdown cover in Europe etc etc but really looking for any experience from anyone who has driven the route from Calais 

thanks in advance
