I'll let you in on a secret. for a place to get totally wasted and shagged out of you brains in total privacy, Cassio is the place. It's massive. Trees everywhere. Great stuff. However, also great for rape and robbing people. But I've only heard about the latter happening every now and then, not the rape.

Now on to the serious stuff. Cha cha cha's is a cafe about three minutes from the met station, expensive and alright food but lovely staff and lovely sitting area.
Tennis courts and swimming pools and a canal and the stream, lovely fun for the kids.
Long and short grass provide good hide and seek and football areas.
Quiet, large, beautiful even in winter.
Great massive trees. Oaks, if I'm not mistaken.
in summer, the swimming pools open which have different depths for different aged kids. Nice playpark (barkchipped) and also decent enough food from an onsite building by the pool (burgers chips crisps drinks lollies that sor tof thing).
