Can anyone rec. a good caravan club site in Cornwall or certified location ?

[fakeblonde]

We have a week booked in a lovely site in Hayle but really need another week somewhere.
There are lots of caravan club certified location sites in Cornwall but would love to hear of any good recommendations befre i start ringing around .
We would need a good shower block and electric - thats about all really .
Love Perranporth , Newquay and St Ives.
Cheers

Have just come across this -hope it's not too late. We go to Penmarlam Sands in Fowey - don't know if it's a cc site. Quiet, just 2 fields and a shop, great loo blocks, walking distance to ferry to gorgeous Fowey.
