Two adults, two children under 7. I quite liked the idea of Butlins in Bognor to be honest, it has everything a family needs, but it actually costs more to stay there than a package holiday abroad 
I'm terrified of flying so like the idea of somewhere within ferry distance, or maybe I'll fly, who knows. Basically, somewhere abroad with the kind of family facilities Butlins offers, but not camping or caravans!
