Booking direct rather than through Eurocamp

[PeachesMcLean]

Does anyone have any experience of booking direct with a campsite rather than using Eurocamp or Keycamp etc? I think I'll get £250+ off my fortnight, but wonder:
a) is it a nightmare to arrange?(we sadly don't speak the local language - italian in this case)
b) are the mobile homes more grim than if you go with a company?

Any opinions welcome. thanks all.

We don't like it too hot either - in fact this is our first time taking all the kids somewhere that is even slightly warmer than here - but we have got fed up with beach holidays in Ireland where you need jumpers and rainjackets!
