Hi Jackyjat
Went here a few years ago with my kids (only hols we have are budget ones :D) and had a lovely time. New Forest on the doorstep, no sandy beach, although only a short drive to Bournemouth, Swanage etc.
Sandy Ballsoops - just noticed you want to avoid commercial sites. Have to admit I do the same, although with this one we did use the pool, and the take away :D other than that it was a base to get into the New Forest, cycling, walking and riding.
