Our first 'Sun' holiday was to rockley park and I was very 'why do people complain about Haven holidays this is lovely' really lovely place, we had a great time.
So, booked two more, Weymouth bay, quite busy but location great, just used caravan as a base. Then Devon Cliffs, never, ever, ever again. Awful, massive place, roughest people I have ever met, left early as could not stay longer than the first day!!
Perrin sands was ok, big site and almost had a heart array k trying to get down the 'path' on the cliff to the beach so I would drive down the coast to the beach instead!!
Loved riveriere sands at Hayle, right on the beach, a small quiet site, have been three times now, loved it. My dc are 2 and 5 so suited us, plenty to do in the area and beach just exceptional.
