Will be arriving in Glasgow and want to visit Dunoon. Option one is to take the ferry from Grenock round trip then travel to Androssan to pick up the ferry to Brodick to spend two days on Arran. We then head north to Fort William. Is there an alternate or better way to do this trip. IE: go straight to Androssan/Arran and catch Dunoon on the way to Fort William. Thanks for any help. Can't wait to see beautiful Scotland.
