go for one of the camping holidays in France or Spain...I can highly recommend La Sirene south of Carcassonne or Sanguli in Salou.
Book direct with sites and book flights separate. Ryanair fly into Carcassonne or Reus near Salou.
Having been to both places, Sanguli shades it...Spain is much more relaxed...beach on the door step, cheaper to eat out. Food is better, Portaventura up the road and its not full of French people
