Good sites for under 5s please, Sandy Balls ish rather than Haven-esque

[Bucketsofdynomite]

We had a lovely time last summer at Sandy Balls but want to go further afield this August (we live in Hampshire ). Our kids will be 2 and 4 and we really appreciated the free play sessions they threw on at Sandy Balls.
Any recommendations?

Camping or mobile home?

oops, sorry camping.

were the play sessions like kids clubs?

or posher?

No you just went along with your child and did playdough whatever was organised.

ooh that sounds nice!

I haven't heard of any sites, I know Haven's kids clubs for little ones are those where parents stay and take part but apart from that......

I'll have a think though.
