This is/was an excellent little park that has been owned and managed by the one family for multiple generations. I've stayed there a few times and the impression I got was that there was excess of cabins/villas and a dearth of sites. It did not have all the "kiddy stuff" of many Big4s and I felt that the site fees were not excessive for a park of its standard.
On each occasion I was there it seemed to me that the occupancy rate of the villas was low so maybe they had and over supply of them.
