Camp Site south of Barcelona

(Moved from the Social Room)

I am taking the wifey and two small boys age 2 and 4 to see the rest of the family in Alicante in the Easter Holidays 24th March 2013. Whilst I am o.k for stop overs in France can anyone recommend a good site not to expensive south of Barcelona. I have looked in the club books and some seem nuts at 40 - 50 euro a night. No free aires please, I want a little more security with the boys.
