santander to vilanova

Hi everyone, we are relatively new to caravaning, have completed a few rallies and three solo trips.

However we are being brave and have boked a trip to Spain this October.  I would appreciate some help on our planned journey from Santander port to Vilanova Park near Barcelona.  Will there be any service stations where it is safe to stay on the way.  Our ferrie doesn't dock in Santander until 18.00 hrs.

Any body stayed at ths park in winter months?
