We stayed in February.  Site was quoet but still busy.  Spotless facilities and freindly staff, as always.  We walked from the site, first day up through the valley to the racecourse and round and down in to Brighton, ending up through The Laines and back along the undercliff to the Marina and then to the site. 8-9 miles.  Next day we went up over the top to Rottingdean, had tea, and walked back along the undercliffe to the Marina. Suspect site might be a bit manic in Summer.  Unable to offer a good review for families on the avbove as we didn't take the family.  There is a kiddie play area. No pub neearby and local housing estate is NOT an architectural triumph! However we shall return to walk up on the South Downs at some time.
