Snowy Mtns tour

I did a tour to the Snowy Mountains early this year, was a great trip but tiring due to the pace/time limit set of 5 days! I would very much like to do the trip again with say 7 days and some slight alterations to the route, mainly the same roads but in different directions of travel on some parts and an extra day in the snowys area itself and the dailey Km's reduced with the other extra day.
