The main decision you have to make in advance is whether to cross the French border into Spain on the east side or the west side of Pyrenees. I always go for the latter, because if you go east side it is busier and you are paying tolls from the moment you enter Spain, all the way down to Valencia. If you cross west side, you can travel on quiet roads toll free all the way to Alicante.
So I would use French motorways (yes, pay the tolls, you can save by using A roads but the slower travelling involved is not worth it in my opinion) and go Calais/Rouen/Le Mans/Tours/Poitiers/Bordeaux/Bayonne. Going through Rouen is a bit tricky, just keep following signs for the motorway.
I don't know how far you want to drive in a day, but there are many hotels just off the motorway a little north of Poitiers serving the Futuroscope attraction. A handy place to stop. I would recommend you aim for Tudela in NW Spain on your second night where I can recommend Hotel bed4U. Very comfortable, great breakfast, secure parking, close to restaurants and cheap fuel nearby. When you cross border at Irun, turn off motorway immediately onto inland road N121A for Pamplona. It's a toll free decent standard road. When you get to Pamplona, follow signs for A15 motorway. This is the only toll section you need take before Alicante, but it's worth it. You only need to travel on it for about 50km, then come off at the A68 Tudela if you're going to Hotel bed4U.
You can now stay on the A road all the way to Zaragoza (A68) to avoid tolls, then filter onto the ring motorway of Zaragoza and take toll free A23 motorway for Valencia. This motorway goes through some high, desolate country with few stops. Look out for good place to stop for lunch, service area Valcarce La Bascula about 50km north of Teruel. It has a really tall sign which stands out on the left for approaching motorists, you can see it several kms before you get there. Reasonable fuel prices, good shop and cafe, menu del dia for about 11 euros!.
It's plain sailing now down to Valencia, then the AP7 motorway south down to Alicante and Torrevieja area.
Good luck.
