Re the Caravan Park, its not to bad. Its probably a lot better then the one on the Melbourne side of Stawell, it has a lot of permanents and some can be a bit exciteable.
There is a video on youtube to give you a better idea: http://www.youtube.com/watch?v=slhrKrRQbSY
Thanks for that timely info. I'm in Echuca (Echuca Holiday Park, nearest to town) at present and intend heading for Grampians either Sunday or Monday for a few days. I'll check that one out.
