Thanks D
I am more or less doing as you suggest in my plans. Stopping at Dumfries House near New Cumnock first night. Then over to Arran via Ardrossan. Driving round Arran and out the other side. Then drive around Kintyre before stopping at the Kilberry Inn. Then to Oban and over to Barra for the Outer Hebrides.
