Going to Spain!

Hi, We have just bought our 1st caravan and want to travel down to Spain for a month or so, ultimately we would like to get towards the Benidorm area, does anyone have any recommendations of the best route and places to stay? we have spoken to a fer people and have mixed reports that sites are closed out of peak season, I have received the club info in traveling abroad but it is always good to chat to people that may have been there too

We did look at using a ferry but the costs seem so high and to be honest if we can plan a good route what better way to see the country we would be traveling through

Any info will be gratefully received, looking forward to hearing from you

P.s. does any one have a handbook for a Swift Challanger 400se?
