More accurate details about your trip to KI. After driving across Fleurieu Peninsula from Adelaide, you reach Cape Jervis where you take a ferry or an hydrofoil.
Here is the B& B in Penneshaw, The Seaview Lodge: http://www.seaviewlodge.com.au Food is a must and you can take your breakfast with other guests. The hosts are very nice and helpful.
Concerning Adelaide, try to find a B& B in Adelaide Hills. Adelaide downtown is not very big and surrounded by parks.
Drive across the Adelaide Hills and taste some wines in McClaren Valley (?), less famous than Barossa Valley but a lot of vineyards.
