Recommended caravan parks in Melbourne

[Sox]

Howdy all,

We need to stay for around 4 nights close to Melbourne mid October.
We've stayed at the Big4 place in Braybrook quite a few times in the past, but they are fairly expensive. It is a nice place though.

2 other places we've inquired with are Wantirna park and Sundowner Springvale.
I have no idea what these places are like.

We're using caravans and don't need a powered site.

Alternatively, if anyone has a big enough property within 20k's of the CBD, and is willing to accommodate 2 cars/caravans for the 4 days with payment, that'd be be pretty cool too.

Let the suggestions roll in....
